Product details
Overview
XPC823EVR75B2 from Freescale Semiconductor is a 75 MHz, 256-pin PBGA mobile computing microprocessor integrating a PowerPC core and a dedicated 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, dual SCCs for Ethernet/HDLC/IrDA, and an integrated video/LCD controller - enabling portable imaging and communication devices with low-power operation.
For engineers reviewing the XPC823EVR75B2 datasheet, XPC823EVR75B2 pinout, XPC823EVR75B2 application, or XPC823EVR75B2 equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for embedded PowerPC system design.
Technical Context
The XPC823EVR75B2 implements a dual-processor architecture: a 32-bit PowerPC core (99 MIPS @ 75 MHz) and a 32-bit scalar RISC communication processor module (75+ MIPS @ 75 MHz) sharing on-chip dual-port RAM and virtual DMA channels. It supports simultaneous execution of application code and embedded signal processing for JPEG compression/decompression, modem, and speech recognition.
Its system interface unit enables dynamic bus sizing (8/16/32-bit), big- and little-endian memory compatibility, and glueless interfacing to DRAM, SRAM, Flash, and SDRAM. The integrated video/LCD controller operates in time-multiplexed mode - supporting NTSC/PAL encoders, TFT, and passive LCD panels - while sharing dual-port memory with the CPM.

FAQ
What is the operating temperature range for the XPC823EVR75B2?
The XPC823EVR75B2 is rated for commercial temperature operation from 0°C to 95°C (junction temperature). This specification aligns with the XPC823ZT75B variant documented in the MPC823TS/D datasheet, confirming its suitability for indoor portable electronics and non-extended industrial environments. The 'EVR' suffix denotes a specific revision and packaging variant within the same thermal envelope.
Does the XPC823EVR75B2 support USB 2.0?
No, the XPC823EVR75B2 supports only USB 1.1 Full-Speed (12 Mbps) in host or peripheral mode. Its USB channel is implemented as a dedicated high-speed serial channel with four endpoints, consistent with the MPC823 family's original 1999 specification. USB 2.0 High-Speed (480 Mbps) capability was not included in this generation of PowerPC microprocessors.
Is the XPC823EVR75B2 pin-compatible with other MPC823 variants like XPC823ZT75B?
Yes, the XPC823EVR75B2 uses the identical 256-ball PBGA package (23×23 mm, 1.27 mm pitch) and shares the same pinout as XPC823ZT75B and XPC823CZT75B. All variants in the 23×23 PBGA 75 MHz family maintain mechanical and electrical pin compatibility, differing only in screening grade (commercial vs. extended temperature) and mask revision.
What development tools are supported for the XPC823EVR75B2?
The XPC823EVR75B2 is supported by Freescale's CodeWarrior Development Studio for PowerPC, along with the MPC823 Evaluation Board (MPC823EVB) and associated debug probes using IEEE 1149.1 JTAG. The on-chip advanced debug interface - including four hardware breakpoints and five watchpoint sources - enables non-intrusive program flow tracking and real-time register inspection during development.
Can the XPC823EVR75B2 run Linux or VxWorks?
Yes, the XPC823EVR75B2 is certified for use with both Linux (via Motorola/Freescale BSPs) and VxWorks. Its 32-bit PowerPC core, MMU with 16 virtual address spaces, and 2 KB instruction/1 KB data caches meet the minimum requirements for full-featured real-time and general-purpose operating systems. Reference designs and board support packages were officially released by Freescale for these kernels.
