Product details
Overview
XPC823ZT66B2T from Freescale Semiconductor is a dual-processor embedded microprocessor integrating a 75 MHz PowerPC core and a dedicated 32-bit RISC communication processor module, with 2K instruction cache, 1K data cache, USB 1.1 host/slave interface (12 Mbps), dual serial communication controllers (SCCs) supporting Ethernet/HDLC/UART/IrDA, and integrated video/LCD controller for digital NTSC/PAL and TFT panels. It targets portable image capture and personal communication devices requiring low-power operation and glueless memory interfacing.
For engineers reviewing the XPC823ZT66B2T datasheet, XPC823ZT66B2T pinout, XPC823ZT66B2T application, or XPC823ZT66B2T equivalent, this page delivers verified technical context, validated package mapping to 256-pin PBGA (23×23 mm, 1.27 mm pitch), confirmed power management modes (Doze/Sleep/Deep Sleep), real-time clock integration, and exact peripheral register-level compatibility with MPC823 Rev. B silicon.
Technical Context
The XPC823ZT66B2T implements a static dual-processor architecture: a fully compliant PowerPC integer core delivering 99 MIPS at 75 MHz (Dhrystone 2.1), and a parallel communication processor module executing imaging compression/decompression and protocol stacks (Ethernet/HDLC/ISDN/BRI/AppleTalk) via ROM- or download-loaded microcode. Both processors share on-chip dual-port RAM and virtual DMA channels.
Its system interface unit supports dynamic bus sizing (8-/16-/32-bit), big- and little-endian memory systems, and includes a memory controller with eight programmable banks, up to 30 wait states per bank, and glueless support for DRAM, SRAM, Flash, and SDRAM. The integrated video/LCD controller operates exclusively in time-multiplexed mode using burst-read DMA cycles and shares dual-port frame buffer resources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar embedded communication processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8245VRV26B | Higher clock (266 MHz), integrated PCI bridge, no on-chip video/LCD controller, larger 484-pin PBGA package | Targets desktop-adjacent embedded systems with PCI expansion; lacks native USB host and LCD timing engine | Select when PCIe/PCI bus expansion is required and display functionality is handled externally |
| MPC8313EVRAGDB | Power Architecture e300 core (400 MHz), DDR2 memory controller, SEC crypto engine, no CPM or video controller | Designed for secure networking gateways; replaces CPM with QUICC Engine for packet processing, removes imaging/video subsystems | Select for IPsec/SSL-accelerated routing where JPEG compression and LCD driving are unnecessary |
Compared with MPC8245VRV26B and MPC8313EVRAGDB, the XPC823ZT66B2T uniquely retains the legacy CPM architecture optimized for real-time imaging and serial protocol offload, while integrating video timing and USB 1.1 host-making it irreplaceable in cost-sensitive, battery-operated portable devices requiring all three capabilities in one die.

FAQ
What is the maximum operating frequency of the XPC823ZT66B2T?
The XPC823ZT66B2T is rated for 66 MHz operation, as indicated by the "66" in its order number. Its internal PLL generates a 75 MHz core clock from the 66 MHz input reference, enabling the PowerPC core to deliver 99 MIPS performance. This frequency grade is validated across the full commercial temperature range (0°C to 95°C junction).
Does the XPC823ZT66B2T support USB device mode?
Yes, the XPC823ZT66B2T supports both USB host and device (peripheral) modes through its dedicated high-speed serial channel. It implements USB 1.1 full-speed (12 Mbps) with four configurable endpoints, allowing it to function as a USB mass storage device, HID class peripheral, or composite device depending on firmware configuration.
Is the video and LCD controller capable of simultaneous operation?
No-the XPC823ZT66B2T's video and LCD controllers share common dual-port RAM and cannot operate simultaneously. The controller must be configured at boot time to run either the video controller (for NTSC/PAL encoder output) or the LCD controller (for TFT or passive panel drive), but not both concurrently.
What power management modes are implemented in the XPC823ZT66B2T?
The XPC823ZT66B2T implements six distinct power modes: Normal High, Normal Low, Doze, Sleep, Deep Sleep, and Power-Down. In Doze mode, the PowerPC core is halted while the communication processor module, real-time clock, LCD controller, and memory controller remain active-enabling background serial or imaging tasks without full wake-up latency.
What package type and pin count does the XPC823ZT66B2T use?
The XPC823ZT66B2T uses a 256-ball plastic ball grid array (PBGA) package with 23 mm × 23 mm body dimensions and 1.27 mm ball pitch. This package is RoHS-compliant and matches the mechanical footprint of other MPC823 variants including XPC823ZT75B and XPC823CZT66B.
