8-bit MCU Minimises Power Consumption

The new MC9S08QB from Freescale Semiconductor is a new entry-level 3V, 8-bit MCU with integrated features designed to minimise power consumption.

TheMCU offers sixmodes of operation, including WEB www.my-ftm.com/090209 low-power wait and low-power run. Extra energy savings are achieved via a precision trimming internal clock source with a 32kHz low-power oscillator, and by a voltage regulator with a fast 6µS wake-up time.

Freescale’s new low-power MCU features up to 8 kbyte of Flash programme memory and up to 512 bytes of SRAM. A range of serial communications controllers are integrated along with an eight-channel ADC, a separate analogue comparator, one two-channel 16-bit timer, one 8-bit modulo timer and an eight-channel keyboard interrupt controller. The MCU parts are available in TSSOP-16, QFN-24 and SOIC-28 packages, supporting up to 24 GPIOs.

 

FEATURES 8kbyte or 4kbyte of Flash memory 512 bytes or 256 bytes of SRAM Eight-channel 10-bit or 12-bit ADC Two-channel 16-bit timer 8-bit modulo timer Eight-channel keyboard interrupt controller Six modes of operation: Stop2, Stop3, Low-Power Wait, Low-Power Run, Wait and Run TSSOP-16, QFN-24 and SOIC-28 packages
