Product details
Overview
MPC823CVR66B2T from Freescale Semiconductor is a dual-processor embedded PowerPC microprocessor with integrated communication processor module (CPM), video/LCD controller, USB 1.1 host/slave interface, and PCMCIA-ATA controller. It delivers 99 MIPS at 66 MHz, features 2K instruction and 1K data caches, supports 0–66 MHz static operation, and targets low-power portable imaging and communications devices.
For engineers reviewing the MPC823CVR66B2T datasheet, MPC823CVR66B2T pinout, MPC823CVR66B2T application, or MPC823CVR66B2T equivalent, key selection criteria include its 256-pin PBGA package, 66 MHz maximum frequency, -40°C to +95°C industrial temperature range, dual-processor architecture for parallel signal processing, and integrated peripherals including SCCs, SMCs, SPI, I²C, and DMA-accelerated LCD/video control.
Technical Context
The MPC823CVR66B2T implements a tightly coupled dual-processor architecture: a 32-bit PowerPC core (99 MIPS @ 66 MHz) and a dedicated 32-bit scalar RISC communication processor module (75+ MIPS @ 66 MHz) sharing on-chip dual-port RAM and virtual DMA channels. The CPM handles protocol offload-including HDLC, UART, IrDA 1.1 (SCC2 only), ISDN BRI/PR, and JPEG compression/decompression-freeing the PowerPC core for application tasks.
Its system interface unit provides dynamic bus sizing (8/16/32-bit), glueless memory controller supporting eight banks with up to 30 wait states, and power management with six modes (Normal High/Low, Doze, Sleep, Deep Sleep, Power-Down). The video/LCD controller shares dual-port memory and supports CCIR-656-compatible digital video output and programmable grayscale/color TFT panel driving.

FAQ
What is the maximum operating frequency of the MPC823CVR66B2T?
The MPC823CVR66B2T is rated for a maximum operating frequency of 66 MHz. This specification is validated under industrial temperature conditions (-40°C to +95°C) and ensures full functionality of all integrated peripherals including the PowerPC core, communication processor module, video/LCD controller, and USB interface. Operation above 66 MHz is not supported and may result in undefined behavior or timing violations.
Does the MPC823CVR66B2T support USB host functionality?
Yes, the MPC823CVR66B2T integrates a full-speed USB 1.1 controller supporting both host and slave modes at up to 12 Mbps with four configurable endpoints. The USB_DP and USB_DM pins provide a differential physical layer that requires no external transceiver for basic cable-connected operation. Host-mode capability enables direct connection to USB keyboards, storage devices, or debug adapters without additional silicon.
What package type and pin count does the MPC823CVR66B2T use?
The MPC823CVR66B2T uses a 256-ball plastic ball grid array (PBGA) package with 17 mm × 17 mm dimensions and 1.00 mm ball pitch. This compact industrial-grade package is distinct from the 23×23 mm variant used in commercial-grade MPC823 derivatives. Its RoHS-compliant construction and thermal characteristics are optimized for convection-cooled portable equipment operating across -40°C to +95°C.
How does the communication processor module (CPM) in the MPC823CVR66B2T improve system performance?
The CPM in the MPC823CVR66B2T executes protocol processing-including HDLC, UART, IrDA 1.1, ISDN, and JPEG compression-in parallel with the PowerPC core using dedicated 32-bit RISC hardware and 8 KB dual-port RAM. This offloads time-critical serial and signal processing tasks, reducing PowerPC core interrupt load by up to 70% and enabling deterministic real-time response in applications like barcode scanning or medical imaging preview.
Is the MPC823CVR66B2T compatible with standard PowerPC development tools?
Yes, the MPC823CVR66B2T is fully compatible with standard PowerPC development tools including CodeWarrior Development Studio, GNU PowerPC toolchain (gcc/gdb), and Lauterbach TRACE32 debug probes. Its IEEE 1149.1 JTAG interface supports boundary-scan testing and real-time debugging, while the advanced on-chip debug mode enables instruction/data watchpoints, branch tracing, and exception trap analysis without performance penalty during MPC823CVR66B2T development.
