NXP Semiconductors MPC875CVR133

Overview

MPC875CVR133 from Freescale Semiconductor is a Power Architecture™-based 32-bit integrated microprocessor with embedded MPC8xx core, dual 8-Kbyte instruction/data caches, MMU, two Fast Ethernet controllers (10/100 Mbps), USB 2.0 host/function interface, security engine (AES/DES/3DES/SHA/MD5), and PCMCIA socket - deployed in ATM edge routers, secure gateways, and industrial communications controllers.

For engineers reviewing the MPC875CVR133 datasheet, MPC875CVR133 pinout, MPC875CVR133 application, or MPC875CVR133 equivalent, key selection criteria include 133-MHz core frequency (2:1 bus mode), 1.8-V core / 3.3-V I/O operation, 256-pin PBGA package, IEEE 1149.1 JTAG debug support, and mandatory reset configuration via HRCW and SIUMCR registers.

Technical Context

The MPC875CVR133 integrates a single-issue 32-bit MPC8xx core with two-way set-associative 8-Kbyte instruction and data caches, 32-entry fully associative TLBs supporting 4/16/512 Kbyte and 8 Mbyte page sizes, and advanced on-chip emulation debug mode. Its CPM includes 8-Kbyte dual-port RAM, four baud-rate generators, and RISC-based serial DMA channels for SCC/SMC offload.

System-level integration includes a memory controller with eight programmable banks (up to 30 wait states), four 16-bit or two 32-bit general-purpose timers, clock synthesizer with PLL, IEEE 1149.1 test access port, and security engine comprising DEU (DES/3DES), AESU (128/192/256-bit keys), and MDEU (SHA-1/SHA-256/MD5/HMAC) with crypto-channel DMA support.

FAQ

What is the maximum operating junction temperature for the MPC875CVR133?

The MPC875CVR133 has a maximum junction temperature (TJ) of 95°C under standard operating conditions, as specified in Table 3 of the hardware specifications. This limit applies when ambient temperature (TA) is maintained at 0°C minimum and thermal design uses a four-layer PCB with RθJA = 29 °C/W. Exceeding this value risks permanent damage to the silicon and invalidates functional guarantees.

Does the MPC875CVR133 support USB host mode with low-speed peripherals?

Yes, the MPC875CVR133 supports USB host mode at both full-speed (12 Mbps) and low-speed (1.5 Mbps) data rates. However, low-speed operation requires an external USB hub - the on-chip transceiver does not provide the necessary current drive or pull-up resistor for direct low-speed device attachment per USB 2.0 specification.

How is the security engine in the MPC875CVR133 initialized after reset?

The MPC875CVR133 security engine requires explicit initialization in boot code: the SIUMCR[DBGC] bit must be set to binary X1 immediately after HRESET deassertion, and the MBMR[GPLB4DIS] and port direction registers (PAPAR, PADIR, etc.) must be configured per Table 7. Failure to execute this sequence disables crypto accelerator access.

Can the MPC875CVR133 operate with a 100-MHz external bus clock?

No. The MPC875CVR133 supports a maximum external bus frequency of 80 MHz in 1:1 mode. At 133-MHz core frequency, it operates exclusively in 2:1 mode (core clock = 2 × bus clock), limiting bus speed to 66.5 MHz - not 100 MHz. Attempting 100-MHz bus operation violates AC timing specifications and causes undefined behavior.

What package type and ball pitch does the MPC875CVR133 use?

The MPC875CVR133 uses a 256-ball plastic ball grid array (PBGA) package measuring 17 mm × 17 mm with 1.27 mm ball pitch. It features an exposed thermal pad on the underside for soldering to the PCB ground plane - critical for achieving the specified RθJB = 20 °C/W thermal performance.
