NXP Semiconductors KMPC862PVR100B

Overview

KMPC862PVR100B from Freescale Semiconductor is a PowerQUICC™ family integrated communications microprocessor featuring a 32-bit MPC8xx PowerPC core, 16-Kbyte instruction cache, 8-Kbyte data cache, and integrated Fast Ethernet Controller (FEC) supporting simultaneous MII and UTOPIA operation. It operates at up to 100 MHz with 3.3 V supply and delivers enhanced ATM functionality via ESAR mode for telecom edge applications.

For engineers reviewing the KMPC862PVR100B datasheet, KMPC862PVR100B pinout, KMPC862PVR100B application, or KMPC862PVR100B equivalent, key selection criteria include its 357-pin PBGA package, 100 MHz CPU frequency in 2:1 bus mode, support for four SCCs and two SMCs, IEEE 1149.1 JTAG debug interface, and thermal performance validated up to 115 °C junction temperature.

Technical Context

The KMPC862PVR100B integrates three major functional modules on a unified 32-bit internal bus: the MPC8xx core processor, System Integration Unit (SIU), and Communications Processor Module (CPM). Its CPM includes a RISC controller with 16 serial DMA channels, 8-Kbyte dual-port RAM, and support for HDLC, UART, SPI, I²C, and TSA-based TDM routing.

It implements full PowerPC architecture compliance with MMU (32-entry ITLB/DTLB), branch prediction, cache coherency on 128-bit blocks, and advanced on-chip emulation. The SIU provides clock synthesis, periodic interrupt timer, software watchdog, low-power stop/sleep/deep-sleep modes, and IEEE 1149.1 test access port.

FAQ

What is the maximum operating frequency of the KMPC862PVR100B and how is it configured?

The KMPC862PVR100B operates at a maximum CPU frequency of 100 MHz in 2:1 bus mode (50 MHz bus clock). This configuration requires setting the MF (multiplier factor) register appropriately and verifying that the external clock source meets jitter specifications (±0.5% for MF < 10). The KMPC862PVR100B datasheet confirms this rating under extended temperature conditions with junction temperature limited to 115 °C.

Does the KMPC862PVR100B support IEEE 1149.1 JTAG debugging, and what capabilities does it provide?

Yes, the KMPC862PVR100B includes full IEEE 1149.1 JTAG test access port with eight hardware comparators: four for instruction address matching, two for data address, and two for data value comparison. Each comparator can generate internal breakpoints, enabling non-intrusive code inspection and real-time trace without halting the KMPC862PVR100B core execution.

How many serial communication controllers (SCCs) does the KMPC862PVR100B integrate, and what protocols do they support?

The KMPC862PVR100B integrates four SCCs (SCC1–SCC4), each supporting HDLC/SDLC, asynchronous UART, synchronous UART, IrDA, BISYNC, AppleTalk, and PPP. SCC4 additionally supports optional UTOPIA Level 1/2 interface. This capability allows the KMPC862PVR100B to concurrently manage multiple WAN protocols such as ATM, Frame Relay, and leased-line connections.

What thermal resistance values apply to the KMPC862PVR100B in a standard four-layer PCB layout?

In a standard four-layer board (2s2p) with vias connecting thermal balls to ground plane, the KMPC862PVR100B exhibits RθJB = 13 °C/W (junction-to-board) and RθJMA = 19 °C/W (junction-to-ambient with 200 ft/min airflow). These values are measured per JEDEC JESD51-6 and JESD51-8 standards and form the basis for thermal modeling in production designs using the KMPC862PVR100B.

Is the KMPC862PVR100B pin-compatible with other members of the MPC862/857T/857DSL family?

Yes, the KMPC862PVR100B shares the same 357-pin PBGA package and pinout with MPC862PVR80B and MPC862PVR66B. All three variants maintain identical signal assignments, power/ground ball mapping, and thermal pad configuration, enabling direct substitution in existing layouts without PCB revision-only firmware and clock configuration adjustments are required.
