80 MHz core with integrated CPM communications engine
The MPC852TZT80A is a single-core, 32-bit PowerQUICC RISC microprocessor from the MPC85xx series, clocked at 80 MHz. Its primary differentiator is the integrated Communications Processor Module (CPM), a dedicated co-processor that offloads serial protocol handling from the main core, freeing it for application code. The CPM supports HDLC/SDLC, PCMCIA, SPI, and UART interfaces, making this part a natural fit for telecom line cards, industrial protocol gateways, and networking equipment where the CPU must manage multiple serial streams without software polling overhead.
Package, power rails, and temperature envelope
Housed in a 256-ball BGA (23x23 mm body), the MPC852TZT80A requires a surface-mount reflow profile typical of 1.0 mm pitch PBGA packages. The I/O voltage is fixed at 3.3 V, which sets the interface level for the DRAM controller, PCMCIA port, and all serial peripherals. The operating temperature range is 0°C to 95°C (ambient), which covers most indoor telecom and industrial control cabinet environments but excludes extended outdoor or under-hood automotive use without active cooling.
Note that this variant is marked as RoHS non-compliant, which may restrict its use in new designs governed by the EU RoHS directive. For RoHS-compliant builds, verify the date-code exemption or evaluate the lead-free suffix variants in the MPC85xx family.
