NXP Semiconductors MPC8280CZUUPEA

Overview

MPC8280CZUUPEA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core, three Fast Communication Controllers (FCCs), four Serial Communication Controllers (SCCs), two UTOPIA II ports, two Multichannel Controllers (MCCs), PCI bridge, USB 2.0 controller, and Transmission Convergence (TC) layer - designed for telecom infrastructure, ATM edge devices, and IMA-based access gateways operating at up to 450 MHz core frequency.

For engineers reviewing the MPC8280CZUUPEA datasheet, MPC8280CZUUPEA pinout, MPC8280CZUUPEA application, or MPC8280CZUUPEA equivalent, key selection criteria include its 480-pin TBGA leaded package, dual PLL architecture enabling independent core/CPM clocking, support for 10/100 Ethernet via MII/RMII, UTOPIA Level 2 interface for ATM SAR, and TC-layer hardware acceleration for inverse multiplexing over ATM (IMA).

Technical Context

The MPC8280CZUUPEA integrates a Power Architecture–compliant G2_LE core with 16 KB instruction and 16 KB data caches, separate 60x and local buses, and a Communications Processor Module (CPM) containing dedicated RISC microcontroller, dual-port RAM, and serial DMA engines. Its CPM supports protocol offload for HDLC, transparent, UART, BISYNC, and Ethernet MAC functions across FCCs and SCCs.

It features two independent PLLs - one for the G2_LE core (2:1 to 8:1 multipliers) and one for the CPM (2:1 to 8:1 multipliers) - enabling asynchronous operation at up to 450 MHz core and 292 MHz CPM frequencies. The device implements a 64-bit 60x bus (up to 100 MHz) and 32-bit local bus (up to 100 MHz), with on-chip memory controller supporting SDRAM, SRAM, Flash, and EPROM.

Key Specifications

Pinout & Package

The MPC8280CZUUPEA is housed in a 480-ball thin BGA (TBGA) package with leaded solder balls (ZU code), measuring 27 mm × 27 mm with 1.27 mm ball pitch. Thermal resistance is RθJA = 16°C/W (natural convection, single-layer board) and RθJB = 6°C/W (junction-to-board).

FAQ

What is the maximum operating junction temperature for the MPC8280CZUUPEA?

The MPC8280CZUUPEA has a maximum rated junction temperature (Tj) of 105°C under recommended operating conditions. This limit applies to commercial temperature grade devices; extended temperature variants support –40°C to 105°C ambient. Thermal design must ensure RθJA × PD + TA ≤ 105°C, with PD including both core (VDD × IDD) and I/O power components.

Does the MPC8280CZUUPEA support USB device mode with full-speed operation?

Yes, the MPC8280CZUUPEA supports USB 2.0 full-speed (12 Mbps) operation in both host and slave (device) modes. In slave mode, it provides four independent endpoints supporting control, bulk, interrupt, and isochronous transfers, with CRC16 generation/checking, NRZI encoding/decoding, and automatic retransmission on transmit error - all implemented in hardware without CPU intervention.

How many TDM interfaces does the MPC8280CZUUPEA support, and what standards are covered?

The MPC8280CZUUPEA supports eight TDM interfaces via two SI blocks (four TDMs each), covering T1, E1, T3/E3, ISDN basic rate (BRI), ISDN primary rate (PRI), pulse code modulation highway, Freescale IDL, GCI, and user-defined serial formats. Each TDM group supports independent frame sync, bit/byte resolution, and transmit/receive routing - enabling flexible time-slot assignment in voice and data concentrators.

Is the MPC8280CZUUPEA pin-compatible with other PowerQUICC II devices like the MPC8270?

No, the MPC8280CZUUPEA is not pin-compatible with the MPC8270. While both use 480-ball TBGA packages (ZU/VV), their pinouts differ significantly due to added functionality in the MPC8280CZUUPEA - including second MCC, TC layer signals, dual UTOPIA ports, and expanded TDM routing. Pin mapping must be verified against the MPC8280EC Rev. 2 pinout table (Section 8) for each specific signal.

What clock configuration options are available for the G2_LE core in the MPC8280CZUUPEA?

The MPC8280CZUUPEA's G2_LE core supports internal clock multiplication ratios of 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 4.5:1, 5:1, 6:1, 7:1, and 8:1 relative to CLKIN. With a 33–100 MHz CLKIN, this enables core frequencies from 166 MHz up to 450 MHz. The ratio is configured via the SYPCR register during boot, and the resulting core clock drives the 60x bus and instruction pipeline independently of the CPM clock domain.
