MPC850DSLCZQ50BU

The MPC850DSLCZQ50BU is a single‑core, 32‑bit microprocessor based on the MPC8xx core architecture, operating at 50 MHz and designed for embedded communications and networking applications. It integrates a Communications Processor Module (CPM) and system peripherals to simplify controller designs for cost‑sensitive remote‑access, telecommunications and industrial networking equipment.

Built for industrial environments, the device supports a 3.3 V I/O interface, DRAM memory controllers and a compact 256‑pin PBGA package, providing a balanced combination of integration, peripheral support and extended operating temperature range.

Key Features

• Core  Single embedded MPC8xx 32‑bit core running at 50 MHz for deterministic embedded processing.
• Communications Processor Module (CPM)  Integrated CPM with an independent RISC communications processor (CP) that off‑loads peripheral and protocol tasks from the main core.
• Serial channel support  CPM supports up to seven serial channels, including SCC(s) for Ethernet/HDLC/ATM, a USB channel, two SMCs, an I2C port and an SPI interface.
• On‑chip peripherals  Single 10 Mbps Ethernet interface and USB 1.x support, plus HDLC/SDLC protocol handling via the CPM.
• Memory and bus  DRAM controller support and an on‑chip dual‑port RAM (series documentation references an 8‑Kbyte dual‑port RAM) to aid data buffering and inter‑processor communication.
• Power and I/O  3.3 V I/O voltage level compatible with standard embedded peripherals.
• Package and mounting  256‑PBGA (23×23) / 256‑BBGA package, surface mount.
• Industrial qualification  Specified operating temperature range of −40°C to 95°C and RoHS compliant for industrial applications.

Typical Applications

• Telecommunications gateways  Integrated CPM, Ethernet and HDLC support make the MPC850 suitable for remote‑access and telecom gateway controllers.
• Embedded networking equipment  Single‑chip communications processing with DRAM controller and USB enables compact networking modules and interface controllers.
• Industrial controllers  Industrial temperature rating and a robust communications peripheral set support deployment in harsh or temperature‑sensitive industrial systems.
• Protocol offload and peripheral bridging  The CPM’s independent CP can off‑load serial and protocol tasks (SCC, SMC, I2C, SPI), simplifying host software and improving system determinism.

Unique Advantages

• Highly integrated communications subsystem: CPM plus dedicated serial channels, Ethernet and USB provide a comprehensive peripheral set that reduces external component count.
• Off‑load capability for protocol processing: The CPM’s independent communications processor handles HDLC/SDLC and serial protocols, freeing the main core for application tasks.
• Industrial temperature range: Rated from −40°C to 95°C for reliable operation in industrial environments.
• Compact package: 256‑pin PBGA (23×23) minimizes PCB footprint while supporting dense I/O routing for embedded boards.
• Standards‑oriented I/O voltages: 3.3 V I/O levels for compatibility with common embedded peripherals and interfaces.
• RoHS compliant: Meets environmental requirements for lead‑free product designs.
