MPC850DEZQ50BU

The MPC850DEZQ50BU is an NXP Semiconductors embedded microprocessor in the MPC850 family, featuring a single 32-bit MPC8xx core running at 50 MHz. Designed for communications-focused embedded systems, it combines a high-performance core with integrated system peripherals to address cost-sensitive networking, remote-access and telecommunications applications.

This device integrates a Communications Processor Module (CPM) and a versatile memory controller to simplify system design, and provides on-chip interfaces such as Ethernet and USB alongside HDLC/SDLC support for common serial protocols.

Key Features

• Core  Single 32-bit MPC8xx core operating at 50 MHz for deterministic embedded processing.
• Communications Processor (CPM)  Integrated CPM and communications coprocessor functionality to off-load peripheral and protocol tasks from the main core.
• Interfaces  On-chip support includes one 10 Mbps Ethernet port, one USB 1.x channel, and HDLC/SDLC serial protocol support for communications applications.
• Memory Support  Integrated DRAM controller to interface with external memory devices.
• Power and I/O  I/O voltage: 3.3 V compatible for common embedded designs.
• Package and Mounting  256-PBGA (23 × 23 mm) surface-mount package for high-density board designs.
• Operating Range  Consumer qualification with an operating temperature range of 0 °C to 95 °C.
• Compliance  RoHS compliant.

Typical Applications

• Communications Equipment  Used in network controllers and remote-access devices where integrated Ethernet and serial protocol support simplifies system architecture.
• Telecommunications Terminals  Suitable for cost-sensitive telecom endpoints that benefit from an on-chip CPM and communications off-load.
• Embedded Networking Appliances  Ideal for small form-factor appliances that require USB connectivity and serial protocol handling alongside an embedded processor.

Unique Advantages

• Integrated Communications Off-load  The on-chip CPM and communications coprocessor reduce CPU overhead for protocol handling and serial channel management.
• On-chip Peripheral Set  Built-in Ethernet (10 Mbps), USB 1.x, and HDLC/SDLC support minimize external interface components and simplify BOM.
• Compact Package  256-PBGA (23×23) package enables dense board layouts while providing the required I/O count for communications applications.
• Design-Ready I/O Level  3.3 V I/O compatibility eases integration with common peripheral devices and level-shifting requirements.
• RoHS Compliant  Meets RoHS requirements for use in lead-free assemblies.
