NXP Semiconductors MPC8270CVRMIBA

Overview

MPC8270CVRMIBA from NXP (formerly Freescale) is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core, 32-bit RISC CPM, three FCCs, four SCCs, PCI bridge, USB 2.0 controller, and 16 KB I/D caches. It operates at up to 450 MHz with separate PLLs for core and CPM, supports 10/100 Ethernet via MII/RMII, and targets telecom edge routers and industrial gateways requiring deterministic real-time packet processing.

For engineers reviewing the MPC8270CVRMIBA datasheet, MPC8270CVRMIBA pinout, MPC8270CVRMIBA application, or MPC8270CVRMIBA equivalent, key selection criteria include its 480-pin TBGA package, 1.45–1.60 V core supply, 3.135–3.465 V I/O supply, support for up to four TDM interfaces, and absence of UTOPIA II and TC layer hardware-distinguishing it from MPC8280.

Technical Context

The MPC8270CVRMIBA integrates a Power Architecture®-compliant G2_LE microprocessor core with separate 16 KB instruction and data caches, and a dedicated 32-bit RISC Communications Processor Module (CPM) with 32 KB dual-port RAM. Its architecture enables concurrent execution of host-level tasks and time-critical communication protocol handling-including HDLC, UART, transparent serial, and Ethernet-without CPU intervention.

It features a 64-bit 60x bus (up to 100 MHz), 32-bit local bus (up to 100 MHz), and compliant PCI 2.2 bridge operating at 66 MHz. Unlike the MPC8280, the MPC8270CVRMIBA omits UTOPIA II ports, TC layer, IMA, and second MCC-retaining only one multichannel controller and four TDM channels across a single SI block.

FAQ

What is the maximum operating frequency of the MPC8270CVRMIBA core?

The MPC8270CVRMIBA supports a maximum core frequency of 450 MHz, achieved using internal PLL multiplication ratios up to 8:1 from the CLKIN input. This frequency is validated under recommended operating conditions (VDD = 1.45–1.60 V, TA = 0–70°C, junction temperature ≤105°C) and enables high-performance packet processing in telecom and industrial applications. The MPC8270CVRMIBA datasheet specifies AC timing parameters for 450 MHz operation across all supported bus configurations.

Does the MPC8270CVRMIBA support UTOPIA II interface?

No, the MPC8270CVRMIBA does not support UTOPIA II interface. According to the official MPC8280EC hardware specification document (Rev. 2, 09/2011), UTOPIA II ports are explicitly excluded from the MPC8270 device family-including MPC8270CVRMIBA-and are only present on the MPC8280 and MPC8275 variants. This omission is a deliberate architectural distinction that reduces pin count and simplifies design for non-ATM applications.

What package type is used for the MPC8270CVRMIBA?

The MPC8270CVRMIBA uses a 480-ball thin-profile ball grid array (TBGA) package, designated as ZU (leaded) or VV (lead-free) in Freescale documentation. It measures 27 mm × 27 mm with 1.0 mm ball pitch and complies with RoHS requirements. This package is distinct from the 516 PBGA used by MPC8280 and is not pin-compatible with VR/ZQ variants.

How many TDM interfaces does the MPC8270CVRMIBA support?

The MPC8270CVRMIBA supports four TDM interfaces, implemented via a single serial interface (SI) block with four TDM channels (TDM2[A–D]). This is confirmed in Section 1.1 of the MPC8280EC specification, which states that MPC8270 and its VR/ZQ variants have "only 1 SI block and 4 TDM ports," whereas MPC8280 supports eight TDM interfaces across two SI blocks.

Is the MPC8270CVRMIBA pin-compatible with the MPC8280CVRMIBA?

No, the MPC8270CVRMIBA is not pin-compatible with the MPC8280CVRMIBA. The MPC8270CVRMIBA uses a 480-ball TBGA package (ZU/VV), while the MPC8280CVRMIBA uses a 516-ball PBGA package (VR/ZQ). Their pin counts, ball layouts, power delivery schemes, and signal allocations differ fundamentally-requiring separate PCB designs and layout validation for each part.
