MC9S08AC32CFUER

8Bit, 32K FLASH, 8K RAM

Overview

The AC family, comprised of pin-compatible 8-bit and 32-bit device duos, is the third family in the Flexis® series. The Flexis series of controllers is the connection point on Our Controller Continuum, where 8- and 32-bit compatibility becomes reality.

The S08AC128/96/60/48/32 pushes the boundaries of the 8-bit architecture performance with 128 KB of flash, three timer/pulse-width modulators PWM, 16-channel, 10-bit analog-to-digital converter ADC and up to 20 MHz in bus frequency. The 8-bit S08AC128/96/60/48/32 are pin-, peripheral- and tool-compatible with the 32-bit MCF51AC256/128 devices. They share a common set of peripherals and development tools to deliver the ultimate in migration flexibility.

_The EMC performance of an application using this microcontroller is dependent on a number of factors that are outside the control of Semiconductors. These factors include but are not limited to industrial design, mechanical design, printed circuit board design and layout, components, connectors, and cables. NXP Semiconductors is unable to guarantee the EMC performance of any microcontroller in a specific application. Careful consideration must be made when designing any application to ensure the necessary level of EMC. For more information on designing robust EMC systems please refer to application note AN2764._
