NXP MCF5272VF66

Coldfire V266 МГц16 КБ (4K x 32)

Features

A block diagram of the MCF5272 is shown in Figure 1-1. The main features are as follows:

? Static Version 2 ColdFire variable-length RISC processor

— 32-bit address and data path on-chip

— 66-MHz processor core and bus frequency

— Sixteen general-purpose 32-bit data and address registers

— Multiply-accumulate unit (MAC) for DSP and fast multiply operations

? On-chip memories

— 4-Kbyte SRAM on CPU internal bus

— 16-Kbyte ROM on CPU internal bus

— 1-Kbyte instruction cache

? Power management

— Fully-static operation with processor sleep and whole-chip stop modes

— Very rapid response to interrupts from the low-power sleep mode (wake-up feature)

— Clock enable/disable for each peripheral when not used

— Software-controlled disable of external clock input for virtually zero power consumption

(low-power stop mode)

? Two universal asynchronous/synchronous receiver transmitters (UARTs)

— Full-duplex operation

— Based on MC68681 dual-UART (DUART) programming model

— Flexible baud rate generator

— Modem control signals available (CTS and RTS)

— Processor interrupt and wakeup capability

— Enhanced Tx, Rx FIFOs, 24 bytes each
