MC68332ACEH25

The MC68332ACEH25 from Freescale Semiconductor is a 32-bit modular microcontroller designed for high-performance data manipulation and peripheral control. It integrates several key modules, including the CPU32 core, a system integration module (SIM), a time processor unit (TPU), a queued serial module (QSM), and 2 Kbytes of static RAM with TPU emulation capability.

This microcontroller supports a maximum system clock speed of 20.97 MHz and can operate with an external clock input or synthesize an internal clock from a reference frequency. Its fully static operation ensures that register and memory contents are unaffected by clock rate changes. The device is built using a high-density complementary metal-oxide semiconductor (HCMOS) architecture, contributing to low basic power consumption, which can be further minimized using the low-power stop (LPSTOP) command.

The MC68332ACEH25 is available in a 132-Pin PQFP package. It supports various operating temperature ranges, including -40°C to +85°C, -40°C to +105°C, and -40°C to +125°C, with clock frequencies of 16 MHz and 20 MHz depending on the specific variant. Standardization of its modules facilitates rapid development for specific applications.
