NXP Semiconductors KMPC866PVR133A

Overview

KMPC866PVR133A from NXP Semiconductors (formerly Freescale) is a 32-bit PowerQUICC™ communications processor integrating an embedded PowerPC core, CPM coprocessor, and Fast Ethernet controller. It operates at 133 MHz CPU frequency with 16 KB instruction cache and 8 KB data cache, supports up to four SCCs and dual SMCs, and delivers ATM-enhanced SAR functionality for edge networking equipment.

For engineers reviewing the KMPC866PVR133A datasheet, KMPC866PVR133A pinout, KMPC866PVR133A application, or KMPC866PVR133A equivalent, this page provides verified electrical specs, thermal limits, cache configuration, bus timing modes, and validated alternative parts for industrial telecom and embedded control designs requiring deterministic real-time communication processing.

Technical Context

The KMPC866PVR133A implements a single-issue 32-bit PowerPC core with MMU, 32-entry ITLB/DTLB, and physically addressed caches supporting lockable 128-bit cache blocks. Its CPM module contains a 32-bit RISC controller, 8 KB dual-port RAM, and 16 SDMA channels dedicated to serial peripheral offloading.

It integrates a system integration unit (SIU) with clock synthesizer, IEEE 1149.1 JTAG debug interface, software watchdog, and memory controller supporting DRAM, SDRAM, SRAM, and flash across eight banks - all operating under 1.8 V core and 3.3 V I/O supply rails with 5-V tolerant pins on select I/O groups.

Key Specifications

Pinout & Package

KMPC866PVR133A is housed in a 357-pin plastic ball grid array (PBGA) package with 1.27 mm pitch, designed for four-layer PCB mounting with dedicated VDD/VSS planes and thermal via arrays beneath the exposed die pad.

FAQ

What is the maximum junction temperature specification for KMPC866PVR133A?

The KMPC866PVR133A has a maximum junction temperature (Tj) of 95 °C under standard operating conditions. This limit applies when ambient temperature is maintained at 0–70 °C and thermal design uses the specified RθJB = 13 °C/W path to the PCB. Exceeding this temperature risks timing violations and accelerated electromigration in the 0.25 µm process technology.

Does KMPC866PVR133A support full-duplex UTOPIA Level 2 operation?

Yes, KMPC866PVR133A supports full-duplex UTOPIA Level 2 operation in both master (ATM side) and slave (PHY side) configurations using its split-bus architecture. This capability is confirmed in Section 3 of the MPC866/MPC859 Hardware Specifications Rev. 2, enabling simultaneous cell transmission and reception without external FIFO buffers.

How many serial DMA channels does KMPC866PVR133A provide?

KMPC866PVR133A provides 16 serial DMA (SDMA) channels allocated across its four SCCs and two SMCs. This is documented in Table 1 and Section 2 of the Freescale MPC866/MPC859 Hardware Specifications, enabling concurrent high-speed data movement for ATM, Ethernet, and serial protocols without CPU intervention.

Is KMPC866PVR133A pin-compatible with MPC859PVR133A?

Yes, KMPC866PVR133A and MPC859PVR133A share identical 357-pin PBGA mechanical footprints and pin assignments per Freescale's mechanical data in Section 15. However, functional differences exist: KMPC866PVR133A exposes four SCCs and TSA signals unused on MPC859PVR133A, requiring firmware and schematic validation before substitution.

What voltage sequencing is required for KMPC866PVR133A during power-up?

KMPC866PVR133A requires VDDL to ramp no faster than VDDH during power-up; VDDL must never exceed VDDH. The absolute maximum difference is 100 mV between VDDL and VDDSYN. Freescale recommends using discrete Schottky diodes (e.g., MUR420) as shown in Figure 4 of the Hardware Specifications to enforce safe sequencing and prevent ESD diode forward biasing.
