Popular control MCUs overcome next-generation challenges

Freescale Semiconductor has enhanced its MC9S08AC MCU family to satisfy advancing demands from target markets and help developers meet IEC 60730/EN 60335 requirements for software safety in embedded control systems.

New features of the MC9S08AC family include an additional timer module and an enhanced Computer Operating Properly (COP) module with independent 1kHz oscillator. Cyclic Redundancy Check (CRC) capability enhances system integrity and allows developers to meet the latest software-safety standards. These advances are combined with a wide operating voltage range from 2.7V to 5.5V for applications such as home appliances, motor controls, and industrial equipment.

Analogue functionality is also increased, with an enhanced 10-bit ADC delivering typical accuracy of ±1LSB and providing separate analogue-power and referencevoltage domains. There is also an automatic Compare function, as well as an asynchronous clock source that can be used to run the ADC when MCU clocks are turned off to save power.

Each device provides multiple communications peripherals and a range of system-security features, including under-voltage detection, Power-On Reset (POR) and security for both Flash and RAM.

 

FEATURES 20MHz CPU internal bus speed ≤60kbytes integrated Flash memory ≤2kbytes RAM Three 16-bit timers Internal clock-generator module with precision trimming Available package options: 64QFP, 64LQFP, 48QFN, 44LQFP, 32LQFP

APPLICATIONS Domestic appliances Motor controls Building automation Industrial controls
