Today, the 32-bit ARM system microcontroller ruled half-Wanjiang Mountain, there are still many semiconductor companies to persist in Reliable and stable, cost-effective 8-bit MCUs, which naturally includes the NXP plan for a long-term support for the S08 series product line. NXP's 8-bit S08MCU products have already included more than 30 products, covering automotive, industrial, consumer applications, etc., providing users with a wide range of functions, prices and product differentiation options.
This love board has got the latest S08pt-Lite evaluation board for NXP semiconductor. Based on NXP new 8-bit MCU S08P series products, the NXP S08P MCU has a man in the 32-bit ARM architecture. Can be equal to one, how to seize market share, let users wish to pay? I hope this article can give you an answer.

The S08pt-Lite Evaluation Board uses a fairly low-profile environmentally friendly package, in addition to NXP logo printed on the box, you don't even know what the package is inside.
Although the box is simple, the basic protection of the board card is still, the NXP S08P-Lite evaluation plate is installed in an anti-static bag, and there is a foam fixation into the cockstakes.
The accessories are not a lot, in addition to the board itself, there is only one MicroSB line for downloading debugging and powering, and a simple to use instructions.
Thanks to the high-speed development of the Internet, many companies are popular with the information directly on the official website, but also access to downloads in the document description, not only environmentally friendly, but also help users get the latest information.
S08pt-Lite Evaluation Board Hardware
The S08pt-Lite evaluation board is very delicate, the entire size and a subway card, but it is different from a lot of minimum system boards, and the S08pt-Lite board is equipped with a lot of unique features, which makes engineers to assess the features of the S08P MCU. Function.
The hardware system block diagram of the S08pt-Lite Evaluation board is shown below. Basically, it can be seen based on the expansion of the board master NXP S08P series MCU, which also contains a board debugger, an external SPI flash, compatible with Arduino Expansion interface, some Common peripheral components such as touch features, LED, buzzers, thermistors, DACs and other functions.
Among them, the board hardware resources are basically distributed on the front, and the following figure is some peripheral interfaces equipped with the board:
There is no metap device on the back of the board, but the pinch-pinch signal is printed with the Arduino interface defines silk screen, which seems little, but it is indeed a great convenient engineer's DIY.
The core master of the S08pt-Lite Evaluation Board is the NXP S08P series microcontroller. This series of product lines integrate various important functions such as touch sensing interface (TSI), EEPROM, and motor control Flex timer, and most S08P helps simplify design and reduce system costs with the same feature ARM system microcontroller.
S08P series microcontroller hardware system block diagram:
The hardware module of different colors in the figure is actually the functions included in different series. The current NXP S08 Series MCU includes various differentialization and various cost-effective extensions, such as PT level (full function + TSI), PA level ( Full-featured) and PL level (cost-effective), S08pt-Lite evaluation board equipped with the most powerful S08PT series of product lines, the most important feature of this product series is TSI and integrated EEPROM, TSI support 16 channel touch sensing, EEPROM supports 500,000 to 1 million write / erasure, simplifying data log management and system design, in addition to this, the main characteristics and advantages of the S08P series can be refer to the table below.
Let's see the other peripheral function sections on the evaluation board based on the S08PT microcontroller.
First of all, it is of course a TSI circuit, as shown in the figure below, you can see that the touch function of NXP is very simple in the design, and the external device does not need to be needed. S08pt has a dedicated hardware module, which can sense the input, reduce software intervention, and TSI can run in all power mode, and the TSI of S08PT has high sensitivity, suitable for industrial and other harsh environments.
Onboard BDM debugger, do not require additional debugger to implement board download debugging, you need to install OSBDM driver, this will be installed automatically when installing the IDE tool, do not need to find yourself to find it.
Potentiometer, buzzer, compatible Arduino expansion interface, this series of combinations can easily take S08P-Lite board directly to the prototype development board, compared to the general minimum system board, obviously much more well.
Although S08pt is an 8-bit microcontroller, but the ability of the author seems to be quite rich, even slightly complicated, such as sensing data acquisition, motor control, alarm device, LCD display, etc. A smart home monitoring device, through this MCU, can achieve design, such as the following smart home security hardware design reference.
Development environment
S08 Series Microcontroller Supported Development Tools for NXP Home's CodeWarrior, the latest version is V10.7, this IDE tool can support ColdFire, ColdFire +, DSC, Kinetis, MPC5XXX, RS08, S08, and S12Z architectures, and can also use The modular installer with the tool is flexible to install the architecture that meets yourself, and reduces the space occupied by the software.
The main features of CodeWarrior:
Eclipse IDE 4.2.1 (JUNO) and CDT 8.1.1
Unlimited assembler
C / C ++ compiler and debugger (some suite is limited)
Integrated flash programmer
Full-chip simulation for DSC, RS08 and S08 derivative models
Processor Expert® software and components
Processor Expert Component Development Environment (Some kits are limited)
Core knowledge debugging (professional version only)
CodeWarrior can support offline full version downloads and online options. If the network speed is also recommended, the online selection version is recommended, the volume requirement is small, you can customize the development package you need to install yourself, flexible.
The installation interface is selected according to your needs.
The CodeWarrior development interface, and Eclipse very similar, users can create, import the corresponding preject.
Used
S08P-LITE can be powered on the plate card by the microSB attached to the development board. If the CodeWarried is already installed, there will be corresponding drivers on the computer, and the board can be downloaded to be downloaded.
After power-on, the board runs the factory built-in program, which is initialized, and then performs self-test test of water lamps, LED, buzzers and other functional self-test.
Compile
debugging
Download software via CodeWarrior.
summary
NXP's latest S08P-Lite development board can be described as small and exquisite, full-featured, and the board is equipped with full-featured + TSI's 8-bit integrated EEPROM's microcontroller S08PT, which is convenient for users to evaluate the microcontroller, and the board is equipped. Resources can also be used directly in prototype development. However, since the board is new, the S08P-Lite board is relatively small, and the officially provided routines or application DEMO is also very small, suitable for enterprise engineers who have a certain basis and itself is looking for high cost replacement programs.
If you are interested in the board, you can purchase (sending the door) through the love board. Especially many industrial-grade solutions that want to find stable and reliable, cost-effective industrial grade solutions may wish to pay more attention.
