NXP  MC68332ACAG25  微控制器, 32位, 模块化架构, Coldfire v1, 25 MHz, 2 KB, 144 引脚, LQFP

The is a highly-integrated 32-bit Modular Microcontroller combines high-performance data manipulation capabilities with powerful peripheral subsystems. The MCU is built up from standard modules that interface through a common intermodule bus IMB. Standardization facilitates rapid development of devices tailored for specific applications. The MCU incorporates a 32-bit CPU CPU32, a system integration module SIM, a time processor unit TPU, a queued serial module QSM and a 2kB static RAM module with TPU emulation capability TPURAM. The MCU can either synthesize an internal clock signal from an external reference or use an external clock input directly. Operation with a 32.768kHz reference frequency is standard. The maximum system clock speed is 20.97MHz. System hardware and software allow changes in clock rate during operation.
