NXP Semiconductors KMPC8272VRTMFA

Overview

KMPC8272VRTMFA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a 32-bit Power Architecture® G2_LE core, dual Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), PCI bridge, USB 2.0 controller, and integrated Security Engine (SEC). It operates at up to 400 MHz, supports 10/100 Ethernet via MII/RMII, and delivers hardware-accelerated DES, 3DES, AES, SHA-1, and MD-5 encryption - deployed in secure network gateways and telecom edge routers.

For engineers reviewing the KMPC8272VRTMFA datasheet, KMPC8272VRTMFA pinout, KMPC8272VRTMFA application, or KMPC8272VRTMFA equivalent, key selection criteria include its 516-pin PBGA (VR package), dual-clock domain architecture (separate PLLs for CPU and CPM), 16 KB I/D caches, 60x bus interface, and SEC-enabled cryptographic throughput for embedded secure communications systems.

Technical Context

The KMPC8272VRTMFA integrates a dual-issue G2_LE core with MMU, instruction/data caches, and floating-point unit, coupled with a dedicated RISC-based Communications Processor Module (CPM) running microcode for protocol offload. Its clock architecture uses independent PLLs enabling asynchronous operation of the CPU (266–400 MHz) and CPM (up to 267 MHz), with programmable multipliers (2:1 to 8:1).

It features a 64-bit 60x bus supporting burst transfers, a 32-bit 66 MHz PCI 2.2-compliant bridge with four DMA channels, eight-bank memory controller for SDRAM/Flash/SRAM, and UTOPIA II interface (MPC8272/8271 only). The integrated Security Engine implements DES, 3DES, AES, SHA-1, MD-5, RC-4, PKEU, and RNG in hardware.

FAQ

What is the maximum operating frequency of the KMPC8272VRTMFA?

The KMPC8272VRTMFA supports a maximum CPU frequency of 400 MHz, achieved using a 5:1 internal core/bus clock multiplier with an 80 MHz CLKIN reference. Its CPM operates up to 267 MHz using a separate PLL and 3:1 multiplier. These frequencies are validated under recommended operating conditions (VDD = 1.425–1.575 V, VDDH = 3.135–3.465 V, TA = 0–70°C) per MPC8272EC Rev. 3.

Does the KMPC8272VRTMFA include a hardware security engine?

Yes, the KMPC8272VRTMFA includes a fully integrated Security Engine (SEC) supporting DES, 3DES, AES, SHA-1, MD-5, RC-4, PKEU, and RNG in hardware. This engine operates independently of the G2_LE core and is accessible via dedicated registers in the memory map - enabling concurrent crypto processing without CPU intervention.

What package type does the KMPC8272VRTMFA use?

The KMPC8272VRTMFA uses a 516-ball PBGA package designated "VR", which is lead-free, measures 27 mm × 27 mm, and has a 1.0 mm ball pitch. It complies with JEDEC MO-251 and is distinct from the ZQ package (lead spheres) used in MPC8275 variants - VR and ZQ are not mechanically interchangeable.

Can the KMPC8272VRTMFA support UTOPIA II interface?

Yes, the KMPC8272VRTMFA supports an 8-bit UTOPIA II interface operating at up to 31 MHz, enabling full-duplex SAR at 155 Mbps. This interface is implemented on dedicated pins (PA[0–7]) and supports AAL0–AAL5, CBR/VBR/UBR/ABR traffic types, and up to 64-K external connections - confirmed in Table 1 and Figure 1 of MPC8272EC Rev. 3.

What is the function of the CPM in the KMPC8272VRTMFA?

The Communications Processor Module (CPM) in the KMPC8272VRTMFA is a 32-bit RISC microcontroller with 16 KB dual-port RAM and 4 KB instruction RAM, executing microcode to offload serial protocol handling. It manages SCCs, SMCs, SPI, I²C, and TDM interfaces independently of the G2_LE core - reducing CPU load for HDLC, UART, and transparent serial tasks.
