Freescale Semiconductor Inc. has extended its popular low-end, 8bit HCS08 microcontroller family with the introduction of the high-performance MC9S08QA4 (QA4) and MC9S08QA2 (QA2) MCUs. Offering 4Kbyte and 2Kbyte of flash memory and 256bytes/160bytes of RAM, respectively, the highly integrated QA4 and QA2 MCUs provide an entry point into the company's S08 family, expanding design flexibility for small-package, low-pin-count devices.

The QA4/QA2 devices are suitable for general-purpose consumer and industrial applications ranging from motor control to portable health care. By achieving a decreased flash memory voltage level of 1.8-3.3V, the 8bit MCUs, says Freescale, step up the performance of battery-packed designs.

The following are the product features of the MC9S08QA4:

  • 4Kbyte flash memory

  • 256 byte RAM

  • S08 8bit CPU at 20MHz

  • Voltage range 1.8-3.3V

  • Flash-based EEPROM

  • 4 GPIO, plus 1 input-only I/O and 1 output-only I/O

  • Enhanced serial communications interface (SCI)

  • Serial peripheral interface (SPI)

  • 10bit ADC with internal reference voltage

  • On-chip temperature sensor

  • Integrated clock source (ICS) up to 10MHz internal bus operation with 2 percent deviation over full temperature and voltage range

  • 1-channel 16bit timers

  • Available in an 8pin package

  • Operating temperature: -40C to +85C

    The QA4 and QA2 devices are available in production quantities. Suggested resale pricing for 10,000-piece quantities of the MC9S08QA4 is 73 cents. Suggested resale pricing for the DEMO9S08QA4E demonstration board is $69.
