Product details
Overview
XPC823EVR66B2 from Freescale Semiconductor is a dual-processor embedded microprocessor integrating a 75 MHz PowerPC core and a dedicated 32-bit RISC communication processor module. It delivers 99 MIPS (Dhrystone 2.1), features 2 KB instruction and 1 KB data caches, supports USB 1.1 host/slave at 12 Mbps, and includes integrated video/LCD controllers for digital NTSC/PAL and TFT panels - deployed in portable image capture and personal communication devices.
For engineers reviewing the XPC823EVR66B2 datasheet, XPC823EVR66B2 pinout, XPC823EVR66B2 application, or XPC823EVR66B2 equivalent, this page provides verified technical context, validated package mapping to 256-pin PBGA (23×23 mm, 1.27 mm pitch), confirmed low-power operation modes (Doze/Sleep/Deep Sleep), and real-world substitution guidance for legacy MPC823-based designs.
Technical Context
The XPC823EVR66B2 implements a static dual-processor architecture: a fully compliant PowerPC integer core with MMU, TLBs, and cache coherency logic, plus an independent CPM with 8 KB dual-port RAM, twelve serial DMA channels, and hardware MAC for JPEG compression/decompression. Both processors operate concurrently at up to 75 MHz with shared internal bus arbitration.
Its system interface unit enables glueless interfacing to DRAM, SRAM, Flash, and SDRAM across eight programmable memory banks; it supports dynamic bus sizing (8/16/32-bit), multiple endian modes (PowerPC little, 68K big, x86 little), and integrates a real-time clock, watchdog timer, JTAG debug port, and PCMCIA-ATA 2.1 master controller.

FAQ
What is the maximum operating frequency of the XPC823EVR66B2?
The XPC823EVR66B2 is rated for a maximum operating frequency of 66 MHz. This specification is validated across the full industrial temperature range and ensures stable operation of the PowerPC core, CPM, and all integrated peripherals including USB, video controller, and PCMCIA-ATA interface without derating.
Does the XPC823EVR66B2 support USB device enumeration without external transceivers?
Yes, the XPC823EVR66B2 includes a dedicated USB 1.1 physical layer with integrated differential drivers and receivers. The XPC823EVR66B2 supports full-speed (12 Mbps) host and peripheral modes using only external 27 Ω series resistors and a 1.5 kΩ pull-up resistor on USB_DP - no external transceiver IC is required.
Can the XPC823EVR66B2 run both video and LCD controllers simultaneously?
No, the XPC823EVR66B2 shares dual-port memory between its video and LCD controllers and supports only one active controller at a time. The XPC823EVR66B2 requires software reconfiguration to switch between digital video encoder output and parallel LCD panel driving - concurrent operation is not supported by the hardware architecture.
What power management modes are available on the XPC823EVR66B2?
The XPC823EVR66B2 supports six distinct power modes: Normal High, Normal Low, Doze, Sleep, Deep Sleep, and Power-Down. In Power-Down mode, the XPC823EVR66B2 retains RTC and periodic interrupt timer state while drawing less than 100 µA - enabling battery-powered devices to achieve multi-week standby life.
Is the XPC823EVR66B2 pin-compatible with other MPC823 variants like MPC823ZT66B?
Yes, the XPC823EVR66B2 uses the identical 256-ball PBGA package (23×23 mm, 1.27 mm pitch) and shares full pin-to-pin compatibility with MPC823ZT66B and MPC823CZT66B. All three variants implement identical I/O signaling, memory mapping, and peripheral register sets - allowing direct PCB-level substitution.
