MPC852TCZT100A

Overview

The MPC852TCZT100A is a microprocessor based on the PowerQUICC family, utilizing an embedded MPC8xx core built on PowerPC architecture. It operates at a maximum frequency of 100 MHz with a 66 MHz external bus. The device features a 32-bit data bus and includes a 4-Kbyte instruction cache and a 4-Kbyte data cache. It integrates a Fast Ethernet Controller (FEC), two serial communication controllers (SCCs), one serial management channel (SMC), and a PCMCIA interface. The processor uses a 1.8 V core voltage and 3.3 V I/O operation.

Feature Summary

• Integrates an embedded MPC8xx core with memory management units and set-associative caches for efficient processing.
• Includes a versatile Communication Processor Module (CPM) with dual-port RAM and serial DMA channels to handle communications tasks.
• Features a Fast Ethernet Controller (FEC) optimized for Ethernet control applications in networking equipment.
• Provides multiple serial interfaces including SCCs, SMC, SPI, and a PCMCIA interface for diverse connectivity options.

Applications

• Ethernet routers and hubs
• VoIP clients
• WiFi access points
• Customer Premises Equipment (CPE)

Procurement Notes

Verify the specific suffix 'TZT100A' against official NXP documentation to confirm package type and temperature range. Ensure compatibility with existing board designs regarding power sequencing between the 1.8 V core and 3.3 V I/O supplies. Confirm that the 5-V tolerant pins meet system interface requirements.

Selection Notes

Select this component for applications requiring integrated Ethernet control and serial communication capabilities within a single chip. Consider the 100 MHz operating speed and the presence of a CPM for handling protocol offloading. Evaluate thermal performance requirements given the junction-to-ambient resistance values specified in the datasheet.

Part Context

This part belongs to the MPC860 PowerQUICC family derivatives. It serves as a subset of the broader Quad Integrated Communications Controller lineup, focusing on cost-effective solutions for networking and controller applications without the full feature set of higher-end models.

Replacement Considerations

Consult the MPC866 PowerQUICC Family Reference Manual for cross-referencing with other family members like the MPC859T or MPC875. Verify pinout and register compatibility before substituting with similar Freescale or NXP processors.
