MPC823VR75B2T

Overview

The MPC823VR75B2T is a mobile computing microprocessor featuring an embedded PowerPC core and a Communication Processor Module (CPM). It operates at 75 MHz with 99 MIPS performance. The device integrates a video/LCD controller, USB interface, PCMCIA-ATA controller, and memory controller supporting up to 256 MB SDRAM. It utilizes a 256-pin BGA package and supports 3.3V I/O with 5V TTL compatibility for general-purpose I/O pins.

Feature Summary

• Dual-processor architecture combining a single-issue PowerPC core with a specialized RISC CPM for parallel imaging and communication processing.
• Integrated peripherals include a dedicated USB channel, two serial communication controllers, two serial management controllers, and a PCMCIA-ATA master interface.
• Advanced power management capabilities with multiple low-power modes including Doze, Sleep, Deep-Sleep, and Power-Down to optimize energy consumption in portable systems.

Applications

• Low-power portable electronic products
• Image capture devices
• Personal communication systems

Procurement Notes

Verify the specific ordering suffix against current NXP or Freescale documentation to confirm package type, temperature range, and lead-free status. Confirm availability as this component may be discontinued or subject to last-time buy notices. Ensure compatibility with existing board designs regarding pinout and voltage levels before procurement.

Selection Notes

Select this processor for applications requiring a balance of general-purpose processing and dedicated communication handling. The integrated LCD and video controllers reduce external component count. Consider the static design and low-power modes for battery-operated devices. Verify software support for the PowerPC architecture and available development tools.

Part Context

The MPC823 belongs to the Motorola/Freescale embedded PowerPC family, designed for mobile computing. It succeeded earlier models by integrating high-performance peripherals like USB and advanced display controllers directly onto the die, reducing system complexity and power requirements for handheld and portable electronics.

Replacement Considerations

Check for official successor parts within the PowerQUICC or Layerscape families. Verify pin compatibility and software migration paths if replacing with newer NXP processors. No direct public substitute part numbers are confirmed in the provided source material.
