MPC862PZQ80B

Product Overview

The Freescale Semiconductor MPC862PZQ80B is a 32-bit, single-core microprocessor in the MPC8xx series, operating at 80 MHz. It is supplied in a 357-BBGA package with a 25x25 body and is intended for surface-mount assembly. The device combines a central processing core with communications-oriented support, including a communications processor module, a DRAM controller, and multiple serial and network interfaces. Its 3.3 V I/O interface and 0°C to 105°C operating temperature range define the basic electrical and environmental constraints for board-level integration.

Key Features

• MPC8xx core with one 32-bit processing unit and an 80 MHz operating speed.
• Integrated communications processor module (CPM).
• DRAM controller for external memory attachment.
• Ethernet support for four 10 Mbps interfaces and one 10/100 Mbps interface.
• HDLC/SDLC, I2C, IrDA, PCMCIA, SPI, TDM, and UART/USART interfaces.
• 3.3 V I/O, surface-mount 357-BBGA package, and 25x25 body size.
• Operating temperature range of 0°C to 105°C ambient.
• No graphics acceleration.

Applications

• Embedded control systems requiring multiple serial communication links.
• Networked communications equipment using Ethernet and TDM interfaces.
• Protocol conversion modules with HDLC/SDLC and UART/USART support.
• Telemetry or data-acquisition systems with DRAM memory and PCMCIA expansion.
• Telecommunications equipment requiring a 32-bit microprocessor and CPM support.

Design & Procurement Notes

Design teams should verify the 357-BBGA landing pattern and 25x25 body size for surface-mount assembly, and ensure the board I/O levels are compatible with the 3.3 V I/O interface. The 0°C to 105°C ambient range should be checked against the intended enclosure thermal environment. Because the device includes a DRAM controller, external DRAM selection, signal integrity, and address mapping must be planned around the MPC8xx core and 80 MHz operating speed. The four 10 Mbps and one 10/100 Mbps Ethernet interfaces, plus HDLC/SDLC, I2C, IrDA, PCMCIA, SPI, TDM, and UART/USART interfaces, should be mapped to the required system functions. No graphics acceleration is available, so graphics acceleration must be addressed separately if required.
