NXP Semiconductors MPC8270CZUQLDA

Overview

MPC8270CZUQLDA from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core (EC603e derivative), 16 KB I-cache and 16 KB D-cache, three Fast Communication Controllers (FCCs), four Serial Communications Controllers (SCCs), PCI bridge, USB 2.0 controller, and integrated memory controller - deployed in carrier-grade TDM-based access gateways and industrial Ethernet routers.

For engineers reviewing the MPC8270CZUQLDA datasheet, MPC8270CZUQLDA pinout, MPC8270CZUQLDA application, or MPC8270CZUQLDA equivalent, key selection criteria include its 480-pin TBGA package, 166–450 MHz core frequency range, dual PLL architecture for independent core/CPM clocking, 3× 10/100-Mbps Ethernet support via MII/RMII, and absence of UTOPIA II, TC layer, and IMA functionality compared to MPC8280.

Technical Context

The MPC8270CZUQLDA implements a split-architecture SoC with a 32-bit Power Architecture-compliant G2_LE integer core and an independent 32-bit RISC Communications Processor Module (CPM) sharing dual-port RAM. Core and CPM operate on separate PLLs, enabling asynchronous clock domains - e.g., 300 MHz core / 150 MHz CPM - optimizing power versus throughput in protocol offload tasks.

Its communication subsystem includes three FCCs supporting IEEE 802.3 10/100 Ethernet (MII/RMII), HDLC up to T3 rates, ATM SAR (excluding MPC8270), and transparent modes; four SCCs compatible with UART, HDLC, SDLC, BISYNC, and synchronous serial protocols; one USB 2.0 full/low-speed controller; and one multichannel controller (MCC) handling up to 128 × 64-kbps TDM channels across four subgroups.

Key Specifications

Pinout & Package

The MPC8270CZUQLDA is housed in a 480-ball TBGA (Thin Ball Grid Array) package with leaded construction (ZU suffix), measuring 27 mm × 27 mm × 1.7 mm, RoHS-compliant per Freescale specification. Thermal resistance is RθJA = 16°C/W (natural convection, single-layer board).

FAQ

What is the maximum operating frequency of the MPC8270CZUQLDA core?

The MPC8270CZUQLDA supports a G2_LE core frequency range of 166 MHz to 450 MHz, determined by the CLKIN reference frequency and programmable internal clock multiplier ratios (2:1 through 8:1). At 100 MHz CLKIN, a 4.5:1 ratio yields 450 MHz core operation - verified in Freescale's MPC8280EC Rev. 2 specification under AC Electrical Characteristics.

Does the MPC8270CZUQLDA support UTOPIA II interface?

No, the MPC8270CZUQLDA does not support UTOPIA II. According to Table 1 and Figure 1 notes in the MPC8280EC Rev. 2 document, UTOPIA II ports are exclusive to MPC8280 and MPC8275 variants - explicitly excluded from MPC8270, MPC8270VR, and MPC8270ZQ devices. This omission is a deliberate product segmentation decision.

How many TDM interfaces does the MPC8270CZUQLDA support?

The MPC8270CZUQLDA supports four TDM interfaces via its single multichannel controller (MCC), as confirmed in Section 1.1 Features and Figure 1 notes: "MPC8270 and the VR and ZQ packages have only 1 SI block and 4 TDM ports (TDM2[A–D])." This enables full T1/E1 trunk termination and ISDN PRI handling without requiring external TDM switches.

What is the package type and ball count of the MPC8270CZUQLDA?

The MPC8270CZUQLDA uses a 480-ball Thin Ball Grid Array (TBGA) package with leaded construction, designated by the 'ZU' suffix per Table 2 of the MPC8280EC Rev. 2 document. Its mechanical dimensions are 27 mm × 27 mm × 1.7 mm, and it is rated for junction temperatures up to 105°C under recommended operating conditions.

Is the MPC8270CZUQLDA pin-compatible with the MPC8280CZUQLDA?

Yes, the MPC8270CZUQLDA and MPC8280CZUQLDA share identical 480 TBGA (ZU) packaging, pin count, and pinout - confirmed in Table 2 and Overview section of MPC8280EC Rev. 2: "references to the MPC8280 and the MPC8270 are inclusive of VR and ZQ package devices unless otherwise specified." Functional differences exist, but PCB layout is interchangeable.
