NXP Semiconductors MPC8270ZUQLDA

Overview

MPC8270ZUQLDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core, 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 telecom edge routers, industrial gateways, and legacy TDM-based access equipment.

For engineers reviewing the MPC8270ZUQLDA datasheet, MPC8270ZUQLDA pinout, MPC8270ZUQLDA application, or MPC8270ZUQLDA equivalent, this page delivers verified package mapping (480 TBGA, leaded), confirmed core/CPM clock separation, validated FCC/SCC protocol support (10/100 Ethernet, HDLC, UART, transparent), thermal resistance data (RθJA = 16°C/W on single-layer board), and precise DC operating conditions (VDD = 1.45–1.60 V, VDDH = 3.135–3.465 V).

Technical Context

The MPC8270ZUQLDA integrates a Power Architecture-compliant G2_LE microprocessor core with separate PLLs for core and CPM domains, enabling independent frequency scaling (core up to 450 MHz, CPM up to 292 MHz). Its communication subsystem includes three FCCs supporting MII/RMII Ethernet and HDLC, plus four SCCs compatible with UART, SDLC, and transparent serial protocols.

It features a 64-bit 60x bus (up to 100 MHz), 32-bit local bus (up to 100 MHz), PCI 2.2-compliant bridge (66 MHz), and dedicated TDM interface supporting four channels - distinguishing it from MPC8280 by omitting UTOPIA II, TC layer, IMA, and second MCC.

FAQ

What is the maximum operating frequency of the MPC8270ZUQLDA core?

The MPC8270ZUQLDA supports a G2_LE core frequency range of 166–450 MHz, achieved via programmable internal PLL multipliers (2:1 to 8:1) referenced to the CLKIN input. At 450 MHz, the core delivers 855 Dhrystone MIPS performance. The actual maximum frequency depends on voltage (VDD = 1.45–1.60 V) and thermal conditions (Tj ≤ 105°C). The MPC8270ZUQLDA datasheet specifies AC timing parameters for 66.67/83.33/100 MHz bus configurations, with corresponding core frequencies derived from PLL settings.

Does the MPC8270ZUQLDA support UTOPIA II interface?

No, the MPC8270ZUQLDA does not support UTOPIA II. According to the MPC8280EC Rev. 2 specification, UTOPIA II ports are exclusive to the MPC8280 and MPC8275 variants. The MPC8270ZUQLDA's FCCs support 10/100-Mbps Ethernet via MII/RMII and HDLC/transparent modes, but lack the UTOPIA physical layer interface required for ATM cell transport. This omission is explicitly noted in Table 1 and Figure 1 notes of the official hardware specification for the MPC8270ZUQLDA.

What package type is used for the MPC8270ZUQLDA?

The MPC8270ZUQLDA uses a 480-ball Thin Ball Grid Array (TBGA) package with leaded solder spheres (ZU designation), measuring 27 mm × 27 mm with 1.27 mm ball pitch. This package is documented in Table 2 of the MPC8280EC Rev. 2 datasheet and is distinct from the 516 PBGA packages (VR/ZQ) used for MPC8275 variants. The ZU package is RoHS-compliant and optimized for thermal dissipation in telecom chassis environments.

Can the MPC8270ZUQLDA operate in slave mode with an external processor?

Yes, the MPC8270ZUQLDA supports slave mode operation. Its CPU core can be disabled via system configuration, allowing the device to function as a peripheral controlled by an external master processor. In this mode, the CPM remains active for serial communications, memory-mapped peripherals remain accessible, and the 60x bus operates under external arbitration. This capability is documented in Section 1.1 ("Features") of the MPC8280EC Rev. 2 specification and enables use cases like coprocessor acceleration or modular system architectures where MPC8270ZUQLDA handles I/O while another SoC manages application logic.

What are the supported USB modes on the MPC8270ZUQLDA?

The MPC8270ZUQLDA integrates a USB 2.0 controller supporting both full-speed (12 Mbps) and low-speed (1.5 Mbps) operation in host and slave modes. In host mode, it supports control, bulk, interrupt, and isochronous transfers with CRC16 generation/checking and NRZI encoding/decoding. In slave mode, it provides four independent endpoints with identical transfer type support. Low-speed operation requires an external hub, and local loopback diagnostics are available at 12 Mbps only - all confirmed in Section 1.1 of the MPC8280EC Rev. 2 datasheet.
