NXP Semiconductors MPC866TCVR100A

Overview

MPC866TCVR100A from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ I communications processor integrating a 32-bit PowerPC core, CPM coprocessor, and Fast Ethernet controller in a single PBGA package. It delivers 4 KB instruction/4 KB data cache, 133 MHz CPU operation, 10/100Base-T MII support, and enhanced ATM SAR functionality for embedded networking applications including DSLAMs and edge routers.

For engineers reviewing the MPC866TCVR100A datasheet, MPC866TCVR100A pinout, MPC866TCVR100A application, or MPC866TCVR100A equivalent, key selection criteria include its dual-voltage operation (1.8 V core / 3.3 V I/O), 357-pin PBGA thermal profile, UTOPIA Level 2 compliance, and deterministic real-time communication processing via dedicated CPM with 8 KB dual-port RAM.

Technical Context

The MPC866TCVR100A implements a single-issue PowerPC 603e-derived core with MMU, 32-entry ITLB/DTLB, and physically addressed caches. Its CPM executes serial protocols independently using a 32-bit RISC controller and 8 KB on-chip dual-port RAM, enabling concurrent HDLC, UART, SPI, I²C, and FEC operations without CPU intervention.

It supports simultaneous MII (10/100Base-T) and UTOPIA Level 2 interfaces, four SCCs (all with serial ATM capability), two SMCs, and full-duplex UTOPIA master/slave operation. The SIU provides clock synthesis, JTAG debug, watchdog, and memory controller supporting DRAM, SDRAM, SRAM, and flash with up to 30 wait states per bank.

FAQ

What is the maximum operating frequency of the MPC866TCVR100A?

The MPC866TCVR100A operates at a maximum CPU frequency of 133 MHz. At this speed, the bus runs in 2:1 mode (66.5 MHz bus clock), supporting high-throughput packet processing. Electrical specifications guarantee stable operation under worst-case voltage (VDDL = 1.9 V, VDDH = 3.465 V) and temperature (Tj = 95 °C) conditions per Freescale Hardware Specifications Rev. 2.

Does the MPC866TCVR100A support both MII and UTOPIA interfaces simultaneously?

Yes, the MPC866TCVR100A supports simultaneous MII (10/100Base-T) and UTOPIA Level 2 operation using the UTOPIA multiplexed bus. This capability is confirmed in Section 2 ("Features") and Table 1 of the MPC866/MPC859 Hardware Specifications, enabling concurrent Ethernet LAN and ATM backhaul without external arbitration logic.

What package type and pin count does the MPC866TCVR100A use?

The MPC866TCVR100A uses a 357-pin plastic ball grid array (PBGA) package with 27 mm × 27 mm body size and 1.27 mm pitch. Mechanical data in Section 15 of the Freescale Hardware Specifications confirms this footprint, which is shared across the MPC866/859 family for PCB design reuse.

How much on-chip memory does the MPC866TCVR100A include for code and data caching?

The MPC866TCVR100A integrates 4 KB of instruction cache and 4 KB of data cache, both implemented as two-way set-associative structures with 128 sets each. This configuration is explicitly defined in Table 1 and Section 2 of the MPC866/MPC859 Hardware Specifications for the "T" variant (e.g., MPC866T, MPC866TCVR100A).

Is the MPC866TCVR100A pin-compatible with other members of the MPC866/859 family?

Yes, the MPC866TCVR100A shares the identical 357-pin PBGA package and pinout with all MPC866/859 family members, including MPC866P, MPC859T, and MPC859DSL. Pin compatibility is verified in Figure 1 (MPC866P block diagram) and mechanical drawings in Section 15 of the Freescale Hardware Specifications Rev. 2.
