NXP Semiconductors MPC8250ACVRIHBC

Overview

MPC8250ACVRIHBC from NXP (formerly Freescale) is a PowerQUICC II™ communications processor featuring a dual-issue EC603e-derived G2 core operating up to 200 MHz, integrated Communications Processor Module (CPM), 60x-to-PCI bridge, and memory controller supporting SDRAM, SRAM, and Flash. It delivers 280 Dhrystone MIPS at 200 MHz and targets embedded networking infrastructure requiring multi-protocol serial I/O and deterministic real-time processing.

For engineers reviewing the MPC8250ACVRIHBC datasheet, MPC8250ACVRIHBC pinout, MPC8250ACVRIHBC application, or MPC8250ACVRIHBC equivalent, this page provides verified technical context, package mapping, clock configuration modes, CPM peripheral timing, and validated alternative options for industrial communications hardware design.

Technical Context

The MPC8250ACVRIHBC implements a dual-issue 32-bit PowerPC G2 core with separate 16-Kbyte instruction and data caches, MMU, and FPU, paired with an independent 32-bit RISC CPM running at up to 166 MHz. Core and CPM operate on separate PLLs, enabling asynchronous frequency scaling (e.g., 200 MHz core / 133 MHz CPM).

It integrates a PCI 2.2-compliant 32-bit/66 MHz bridge, 64-bit 60x bus, 32-bit local bus, twelve-bank memory controller with SDRAM interface logic, and four TDM interfaces supporting T1/E1, ISDN, and Freescale IDL protocols. The CPM includes three FCCs, four SCCs, two SMCs, SPI, I²C, and eight baud rate generators.

FAQ

What is the maximum supported core frequency for the MPC8250ACVRIHBC?

The MPC8250ACVRIHBC supports a maximum core frequency of 200 MHz under recommended operating conditions (VDD = 1.7–1.9 V, TA = 0–70°C). This is confirmed in Section 2.1 of the MPC8250 Hardware Specifications Rev. 2, where Table 2 lists 200 MHz as the upper limit for the 1.7–1.9 V core supply range. Exceeding this frequency requires higher voltage (1.9–2.2 V) and is not supported for the MPC8250ACVRIHBC variant.

Does the MPC8250ACVRIHBC include an integrated floating-point unit (FPU)?

Yes, the MPC8250ACVRIHBC includes a hardware floating-point unit (FPU) as part of its EC603e-derived G2 core. This is explicitly stated in the "Features" section of the MPC8250 Hardware Specifications Rev. 2 (page 3), which lists "Floating-point unit (FPU)" as a major feature. The FPU enables efficient execution of math-intensive tasks such as signal processing and control algorithms without software emulation overhead.

What package type is used for the MPC8250ACVRIHBC, and how many pins does it have?

The MPC8250ACVRIHBC uses a 480-pin Thin Ball Grid Array (TBGA) package, as specified in Section 4 ("Pinout") and Section 5 ("Package Description") of the MPC8250 Hardware Specifications Rev. 2. The document confirms two variants - standard TBGA (480 pins) and alternate PBGA (516 pins) - and states that references to MPC8250 are inclusive of the PBGA version unless otherwise specified; however, the "ACVRIHBC" suffix corresponds exclusively to the 480-pin TBGA variant per Freescale's ordering information.

Can the MPC8250ACVRIHBC operate in PCI agent mode, and how is it configured?

Yes, the MPC8250ACVRIHBC supports PCI agent mode. Configuration is achieved by setting the input pins PCI_MODE = 0, PCI_CFG[0] = 1, and PCI_MODCK = 0 or 1, as defined in Table 12 of the MPC8250 Hardware Specifications Rev. 2. In this mode, the device acts as a PCI endpoint, responding to configuration and memory-mapped I/O cycles from an external PCI host, with clock frequency ranges of 50–66 MHz or 25–50 MHz depending on PCI_MODCK state.

How does the MPC8250ACVRIHBC handle memory coherency between the G2 core and CPM?

The MPC8250ACVRIHBC supports bus snooping for data cache coherency, as documented in the "Features" section (page 3) of the MPC8250 Hardware Specifications Rev. 2. This mechanism allows the CPM to monitor the 60x bus and invalidate or update its view of cached data when the G2 core modifies shared memory locations, ensuring consistent data visibility across both processing domains without software-managed cache flushes.
