MPC860DTCZQ50D4

Overview

The MPC860DTCZQ50D4 is a microprocessor IC from the NXP Semiconductors MPC86xx series. It features a single-core, 32-bit PowerPC architecture operating at a maximum clock frequency of 50 MHz. The device is housed in a 357-ball PBGA package measuring 25x25 mm. It operates with a supply voltage of 3.3 V and supports an industrial temperature range from -40°C to +95°C TJ. Key internal components include 4 KB instruction cache, 4 KB data cache, and an integrated Communications Processor Module (CPM).

Feature Summary

• Integrates a PowerQUICC processor core with dedicated communication capabilities via the CPM.
• Supports multiple serial communication protocols including Ethernet, HDLC/SDLC, I2C, SPI, UART, and PCMCIA.
• Features a complete static design allowing for flexible bus sizing across 8, 16, and 32 bits.

Applications

• Network controller applications requiring integrated processing and peripheral management.
• Telecommunications equipment utilizing serial communication controllers.
• Industrial control systems needing robust interface support.

Procurement Notes

Verify component authenticity through authorized distributors or official NXP channels due to legacy status. Confirm specific mask set revisions and manufacturing dates against current inventory records. Ensure handling procedures account for moisture sensitivity levels as indicated in the datasheet. Validate that the 357-BBGA package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this model when a 50 MHz PowerPC solution with extensive serial interfaces is required. The MPC860D variant specifically offers two Serial Communication Controllers (SCCs) compared to four in the standard T version. Consider the thermal performance within the specified junction temperature range. Evaluate the 3.3 V I/O compatibility against system voltage levels to ensure proper signal integrity without additional level shifting.

Part Context

This component belongs to the MPC86xx family of PowerQUICC processors designed for networking and communications. It shares architectural similarities with other members like the MPC860T and MPC860DT but differs in specific peripheral counts and cache configurations. The MPC860 series provides a balance of processing power and integrated connectivity for embedded network tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The MPC860 series is listed as no longer manufactured. Designers should consult NXP for end-of-life transition strategies or equivalent newer architectures.
