NXP Semiconductors MPC8250ACZQIHBC

Overview

MPC8250ACZQIHBC from NXP (formerly Freescale) is a PowerQUICC II™ communications processor integrating a 200 MHz dual-issue PowerPC G2 core, a dedicated 32-bit communications processor module (CPM), and integrated 60x/PCI/local bus interfaces. It delivers 280 Dhrystone MIPS at 200 MHz, supports IEEE 802.3 10/100-Mbit Ethernet via three FCCs with MII, and operates with separate 1.8 V core and 3.3 V I/O supplies for optimized power management in telecom edge routers.

For engineers reviewing the MPC8250ACZQIHBC datasheet, MPC8250ACZQIHBC pinout, MPC8250ACZQIHBC application, or MPC8250ACZQIHBC equivalent, key selection criteria include its 480-pin TBGA package, dual PLL architecture enabling independent CPM/core clocking (e.g., 133 MHz CPM / 200 MHz core), support for SDRAM/Flash/SRAM glueless memory interfaces, and compliance with PCI Specification 2.2 up to 66 MHz.

Technical Context

The MPC8250ACZQIHBC implements a split-architecture design: the G2 core handles general-purpose processing and MMU-managed memory access, while the CPM offloads protocol-intensive tasks including HDLC, UART, SPI, I²C, TDM, and Ethernet framing-communicating via 32 KB on-chip dual-port RAM and dedicated serial DMAs. Its 60x bus provides 64-bit data width at up to 200 MHz, supporting burst transfers and ECC/parity for mission-critical reliability.

System-level timing is managed by the SIU, which integrates a real-time clock, watchdog timer, JTAG test port, and programmable clock synthesizer with configurable PLL multipliers (core: 1.5×–6×; CPM: 2×–6×). The device supports local bus mode (default), PCI host, and PCI agent configurations determined at power-on reset via MODCK[1–3] and PCI_MODE pins.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MPC8250ACZQIHBC core?

The MPC8250ACZQIHBC supports a maximum core frequency of 200 MHz under recommended operating conditions (VDD = 1.7–1.9 V, TA = 0–70°C). This is achieved using a 33 MHz input clock with a 6× PLL multiplier or a 66.66 MHz input with a 3× multiplier, as defined in Table 13 of the MPC8250EC Rev. 2 specification. Higher frequencies require voltage scaling per Table 2.

Does the MPC8250ACZQIHBC support PCI Express?

No, the MPC8250ACZQIHBC does not support PCI Express. It implements a conventional PCI 2.2 interface with 32-bit/66 MHz capability, compliant with the PCI Local Bus Specification Revision 2.2. The device functions as either PCI host or agent depending on PCI_MODE pin configuration, but lacks PCIe PHY, link training, or transaction layer logic.

How many serial communication controllers does the MPC8250ACZQIHBC integrate?

The MPC8250ACZQIHBC integrates four Serial Communications Controllers (SCC1–SCC4), each functionally identical to those on the MPC860. These support UART, HDLC/SDLC, BISYNC, transparent, and Ethernet MAC modes. Additionally, it includes two Serial Management Controllers (SMC1/SMC2), one Serial Peripheral Interface (SPI), and one Inter-Integrated Circuit (I²C) controller.

What package type is used for the MPC8250ACZQIHBC?

The MPC8250ACZQIHBC uses a 480-pin Thin Ball Grid Array (TBGA) package measuring 19 mm × 19 mm with 1.0 mm ball pitch. This is the standard PowerQUICC II package variant, distinct from the 516-pin PBGA option. The TBGA variant is explicitly referenced in Freescale documentation as the baseline configuration for MPC8250EC Rev. 2.

Can the MPC8250ACZQIHBC operate in slave mode with an external master processor?

Yes, the MPC8250ACZQIHBC supports slave mode operation. The CPU core can be disabled via software or hardware control, allowing the device to function as a peripheral controlled by an external master processor through the 60x or local bus interfaces. In this mode, the CPM remains fully operational for protocol processing, enabling use as a dedicated communications coprocessor.
