MC9S08PA8VWJR is an 8-bit 8-pin microcontrollers series developed by Freescale Semiconductor. As a member of the S08 family, the MC9S08PA8VWJR series is specially designed for portable applications with low power requirement on the market today. In particular, the MC9S08PA8VWJR series provides reliable, low power operation and integrated peripherals for application in consumer, industrial, medical and other embedded applications.

Application Field

The MC9S08PA8VWJR series is ideal for applications where low power requirement is considered essential. The devices integrated peripherals include an analog comparator, flexible serial communications interface module (SCI), 1 to 4 channels 8-bit timer and a 10-bit analog-to-digital converter (ADC). These features enable applications such as:

• Consumer applications: Wireless remote controls, security systems, personal medical devices, etc.
• Industrial applications: Light-controlling systems, process monitoring systems, data logging, etc.
• Medical applications: Portable healthcare systems and medical monitoring devices.

Working Principle

The MC9S08PA8VWJR series is based on the S08 core and works in conjunction with Freescale CodeWarrior IDE. The core can execute up to 4 instructions in one instruction cycle which provides efficient operation at a maximum speed of 5 MHz. The architecture includes enhanced instruction set, on-chip memory and integrated peripherals.

The on-chip memory consists of up to 8KB Flash program memory and up to 1KB data EEPROM. The Flash program memory is used for storing user application code and system information. The data EEPROM is used for storing data that can survive system power-off restart.

The MC9S08PA8VWJR series integrates up to four channels 8-bit timer and a 10-bit analog-to-digital converter (ADC). The timers are used for applications such as event control, waveform generation and pulse width modulation. The ADC allows for conversion of external physical signals into digital values for processing by the S08 core.

The integrated flexible serial communications interface module (SCI) enables full-duplex communications between multiple serial communication devices such as LCD modules, CAN bus, modems and other transceivers. This feature allows for communication between two or more nodes that can communicate with each other using a dedicated serial protocol.

In conclusion, the MC9S08PA8VWJR series provides a wide range of features and benefits that make it an ideal choice for low power applications. With its low power consumption, robust and integrated peripherals, the MC9S08PA8VWJR series is suitable for a variety of embedded applications.
