NXP Semiconductors MPC880VR80

Overview

MPC880VR80 from Freescale Semiconductor is a PowerQUICC II-class integrated communications processor combining a 32-bit MPC8xx core, dual Fast Ethernet controllers (FEC), USB 2.0 full-/low-speed interface, serial communication controllers (SCCs), serial management channels (SMCs), and UTOPIA L2-compliant ATM interface - all in a single 357-pin PBGA package operating at 80 MHz bus frequency and 1.8 V core / 3.3 V I/O.

For engineers reviewing the MPC880VR80 datasheet, MPC880VR80 pinout, MPC880VR80 application, or MPC880VR80 equivalent, this page delivers verified technical context, exact pin-level circuit roles, real-world timing and power specifications, validated alternative parts for networking controller designs, and supply-chain support details specific to industrial telecom and embedded gateway use cases.

Technical Context

The MPC880VR80 implements a unified 32-bit Power Architecture™ core with 8-Kbyte instruction and 8-Kbyte data caches (two-way set-associative), 32-entry ITLB/DTLB, and MMU supporting 4/16/512 Kbyte and 8 Mbyte page sizes. It integrates a Communications Processor Module (CPM) with 8-Kbyte dual-port RAM, four baud rate generators, and RISC-based serial DMA control for SCC/SMC offloading.

Its system integration unit (SIU) provides clock synthesis, IEEE 1149.1 JTAG debug, periodic interrupt timer, software watchdog, and memory controller supporting eight banks with dynamic bus sizing (8/16/32-bit), up to 30 wait states per bank, and glueless interfacing to DRAM, SRAM, Flash, and EPROM. The MPC880VR80 omits the security engine present in MPC885 but retains full UTOPIA L2 and serial ATM capability on SCC4.

Key Specifications

Pinout & Package

The MPC880VR80 is housed in a 357-ball plastic ball grid array (PBGA) package with 19 × 19 ball array, 1.27 mm pitch, and exposed thermal pad. Ball assignment follows Freescale's standard MPC880 pinout layout per MPC885EC Rev. 7, with dedicated VDD/VSS balls distributed across all four sides for low-impedance power delivery.

Equivalent & Alternatives

The following parts are listed as comparable options for similar communications processor applications.

Compared with MPC885VR80, MPC880VR80 removes security acceleration and one SCC to reduce cost and power while retaining dual FEC, USB, and full UTOPIA L2 - making it optimal for unsecured ATM/Ethernet aggregation. Versus MPC875VR80, MPC880VR80 adds USB, second FEC, and UTOPIA at modest power increase, enabling richer connectivity in telecom edge nodes.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors since 2015) was a fabless semiconductor company specializing in embedded processors, analog, and connectivity solutions for automotive, industrial, and networking markets.

The MPC880VR80 belongs to the PowerQUICC II family - designed specifically for cost-sensitive, high-integration communications controllers in DSL, VoIP, and industrial bridging applications where dual Ethernet, ATM, and USB coexistence is required without cryptographic overhead.

FAQ

What is the maximum operating junction temperature for MPC880VR80?

The MPC880VR80 has a maximum junction temperature (TJ) of 95 °C under standard-grade operating conditions, as specified in Table 3 of the MPC885EC Rev. 7 hardware specification. This limit applies when ambient temperature (TA) is maintained at 0–70 °C and thermal design ensures RθJA ≤ 37 °C/W on a single-layer board. Exceeding 95 °C risks permanent reliability degradation; extended-grade variants support up to 100 °C TJ.

Does MPC880VR80 support USB host functionality?

Yes, the MPC880VR80 supports USB host controller mode per Section 2.7 of the MPC885EC Rev. 7 specification. It handles control, bulk, interrupt, and isochronous transfers at both 12 Mbps (full-speed) and 1.5 Mbps (low-speed), with automatic preamble generation and loop-back diagnostics. Low-speed operation requires an external hub, and the USB interface shares pins with other peripherals - configuration is software-controlled via USB registers.

How many serial communication controllers (SCCs) does MPC880VR80 include?

The MPC880VR80 includes two serial communication controllers (SCCs), as confirmed in Table 1 of the MPC885EC Rev. 7 document. This is a key distinction from the MPC885VR80, which includes up to three SCCs. Both SCCs support HDLC/SDLC, UART, IrDA, BISYNC, and serial ATM; SCC4 additionally provides the UTOPIA L2 interface for ATM PHY connection.

Is MPC880VR80 pin-compatible with MPC885VR80?

No, MPC880VR80 is not pin-compatible with MPC885VR80. Although both use the same 357-ball PBGA package footprint and share most signal assignments, the MPC885VR80 adds dedicated security engine interface signals (e.g., CHA_CLK, CHA_RST, CHA_INT) and a third SCC (SCC3) that occupy balls unused on MPC880VR80. Board-level replacement requires PCB redesign to accommodate these extra connections.

What power supply sequencing is required for MPC880VR80?

MPC880VR80 requires strict power sequencing: VDDL (core) must never exceed VDDH (I/O) during power-up or power-down, and both must remain within absolute max ratings (VDDL ≤ 1.9 V, VDDH ≤ 3.465 V). Freescale recommends using Schottky diodes (e.g., MUR420) between VDDH and VDDL rails as shown in Figure 5 of MPC885EC Rev. 7 to enforce this constraint and prevent ESD diode forward-biasing and latch-up.
