8-bit automotive microcontrollers with liquid crystal display driver

Freescale Semiconductor launched S08, an automotive microcontroller (MCU) family designed for entry-level instrument clusters and heating, ventilation and air conditioning (HVAC) controls.

Featuring an integrated liquid crystal display (LCD) driver, the new 8-bit S08LG32 MCUs provide a cost-effective solution for LCD-based body applications in value-line vehicles. The devices can also be used in two/three-wheeled vehicles including motorcycles and scooters.

S08LG32 MCU family features include:

1. The S08LG32 family includes five automotive-qualified 5-volt devices
2. Up to 40 MHz HCS08 CPU core
3. Up to 32 KB on-chip dual flash
4. Up to 2 KB on-chip RAM
5. 8-bit modulo timer (MTIM) with configurable clock inputs
6. Two serial communication interface (SCI) modules
7. Up to 16-channel 12-bit resolution successive approximation analog-to-digital converter (ADC)
8. One internal clock source (ICS): precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage
9. One serial peripheral interface (SPI) module
10. One inter-integrated circuit (I2C) module
11. LCD driver, configurable up to 8 x 37 or 4 x 41; active in lowest power mode; all LCD pins are multiplexed with general-purpose I/Os (GPIOs)
12. One 2-channel and one 6-channel timer/pulse-width modulator (TPM), which can drive stepper motors
13. Real-time background debug mode (BDM) with in-circuit emulation (ICE)
14. Up to 69 standard GPIOs
15. Eight keyboard interrupts (KBI) and one IRQ interrupt with selectable polarity
16. 8-bit real time counter (RTC) with low-power operation and wake up
17. Two temperate range options: -40 degrees C to +85 degrees C and -40 degrees C to +105 degrees C
18. Package options scaling from 48 to 80 pins.
19. Designed to deliver enhanced electromagnetic interference (EMI) and electromagnetic compatibility (EMC) performance.

Availability: Initial samples of the S08LG32 MCUs are available today to selected automotive customers. General market support is planned to be available in the second quarter of 2009.

Freescale plans to offer MC9S08LG32 family demonstration boards and instrument cluster reference designs for the S08 families in Q2 2009.
