Freescale introduces 5 V-capable, automotive-qualified eight-bit MCUs

Freescale Semiconductor has introduced a family of 5 V microcontrollers based on Freescale’s eight-bit HCS08 core. Devices in the MC9S08AW family target automotive and industrial applications.

"The MC9S08AW family is the first 5 V HCS08 microcontroller and the first to be fully qualified for the automotive industry," says Mike McCourt, vice president and general manager of Freescale's microcontroller business. The devices’ strengths include low power, EMC performance and brown-out detection for controlled power-on reset in the event of a brown-out or power failure.

Other features include a 20 MHz maximum bus frequency; options for 16K, 32K and 60K integrated third-generation Flash memory; an on-chip debug/emulation interface; an internal clock generator accurate to ±2% over operating conditions; a 10-bit, 16-channel A/D converter; two timers with a total of eight programmable channels; up to 54 general-purpose I/O lines, plus various communications options and system protection features. The devices are qualified for operation from -40 to +125°C and available in 64-pin QFP and LQFP and 48-pin QFN and LQFP packages.
