MPC850ZQ50BU

The MPC850ZQ50BU is a single‑core, 32‑bit embedded microprocessor in the MPC8xx family, running at 50 MHz and supplied in a 256‑pin PBGA (23×23) package. It combines an embedded MPC8xx core with integrated system functions targeted at controller, communications and networking applications.

Designed for cost‑sensitive remote‑access and telecommunications applications, the device integrates a Communications Processor Module (CPM), DRAM controller and standard I/O interfaces to simplify system design and off‑load peripheral tasks from the main core.

Key Features

• Core & Architecture  Embedded single‑issue MPC8xx core implementing the PowerPC architecture, 32‑bit, 1 core.
• Operating Speed  50 MHz core frequency for embedded control and communications tasks.
• Voltage  3.3 V I/O supply specification.
• Integrated Communications Processor (CPM)  On‑chip CPM provides a dedicated communications RISC processor to off‑load peripheral and protocol handling.
• Serial and Peripheral Interfaces  Includes USB 1.x (1), Ethernet support (10 Mbps, 1), HDLC/SDLC and additional serial channels described by the CPM (SCCs, SMCs, I2C, SPI as supported by the MPC850 family).
• Memory Subsystem  DRAM controller plus family‑level support for an 8‑Kbyte dual‑port RAM as documented for the MPC850 series.
• Package & Mounting  256‑PBGA (23×23) package, surface mount.
• Operating Temperature  0 °C to 95 °C.
• Compliance  RoHS compliant.

Typical Applications

• Communications & Networking  Use as an integrated controller for networking nodes and communication endpoints where on‑chip CPM and Ethernet/HDLC support simplify protocol handling.
• Remote‑Access and Telecommunications  Designed for cost‑sensitive remote access equipment and telecom applications that benefit from an integrated communications subsystem.
• Embedded Controllers  Suitable for embedded control applications requiring a compact 32‑bit MPC8xx core with standard serial and USB connectivity.

Unique Advantages

• Integrated Communications Subsystem: The CPM provides a dedicated communications processor to off‑load peripheral tasks and handle multiple serial channels.
• On‑chip Memory Support: DRAM controller plus documented 8‑Kbyte dual‑port RAM in the MPC850 family reduce external memory complexity.
• Standard I/O Set: Built‑in Ethernet, USB 1.x and HDLC/SDLC interfaces enable common connectivity options without extensive external logic.
• Compact PBGA Package: 256‑pin PBGA (23×23) surface‑mount package supports high I/O density in space‑constrained designs.
• RoHS Compliant: Meets RoHS environmental requirements for compliant manufacturing.
• Wide Commercial Temperature Range: Rated for operation from 0 °C to 95 °C for typical commercial and industrial ambient conditions.
