NXP Semiconductors MPC8271CZQTIEA

Overview

MPC8271CZQTIEA from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a 32-bit Power Architecture® G2_LE core (266–400 MHz), dual 16 KB instruction/data caches, integrated CPM with three SCCs and two FCCs, PCI bridge (32-bit/66 MHz), USB 2.0 controller, and UTOPIA II interface - deployed in telecom edge routers and industrial gateways requiring deterministic real-time packet processing.

For engineers reviewing the MPC8271CZQTIEA datasheet, MPC8271CZQTIEA pinout, MPC8271CZQTIEA application, or MPC8271CZQTIEA equivalent, key selection criteria include its 516-pin PBGA (ZQ package), dual-clock domain architecture (separate core/CPM PLLs), absence of integrated security engine (SEC), and support for ATM SAR at 155 Mbps via UTOPIA.

Technical Context

The MPC8271CZQTIEA implements a dual-issue G2_LE core derived from the MPC603e microprocessor, with physically addressed, four-way set-associative caches and a compliant MMU. Its CPM executes microcode-driven communication protocols independently of the main core using 16 KB dual-port RAM and 4 KB instruction RAM.

AC timing is defined across four bus frequencies (66.67/83.33/100/133 MHz) with load-dependent specifications (50 pF for max delay, 10 pF for min delay). The device supports programmable clock multipliers (core: 2×–8×; CPM: 2×–8×) and operates with separate 1.5 V core and 3.3 V I/O supplies.

FAQ

Does MPC8271CZQTIEA include an integrated security engine (SEC)?

No, MPC8271CZQTIEA does not integrate a security engine. Unlike MPC8272CZQTIEA and MPC8248CZQTIEA, the MPC8271CZQTIEA omits the SEC block entirely. Encryption must be handled externally or in software. This omission reduces die size, power consumption, and cost - aligning with applications where hardware crypto acceleration is unnecessary, such as ATM aggregation without IPsec.

What is the maximum supported CPU frequency for MPC8271CZQTIEA?

The MPC8271CZQTIEA supports a maximum CPU frequency of 400 MHz, achieved using a 50 MHz CLKIN with an 8× core PLL multiplier or a 66.67 MHz CLKIN with a 6× multiplier. This frequency is validated under recommended operating conditions (VDD = 1.425–1.575 V, TA = 0–70°C) and requires adequate thermal management per the 19°C/W junction-to-board resistance spec.

Which package type does MPC8271CZQTIEA use, and what are its key mechanical features?

MPC8271CZQTIEA uses the ZQ package: a 516-ball lead-sphere PBGA measuring 27 mm × 27 mm with 0.8 mm ball pitch. It complies with JEDEC MO-251, supports lead-free assembly, and requires controlled-collapse chip connection (C4) reflow profiles. Thermal resistance values are RθJB = 11°C/W (junction-to-board) and RθJC = 8°C/W (junction-to-case).

Can MPC8271CZQTIEA operate in both PCI host and agent modes?

Yes, MPC8271CZQTIEA's 60x-to-PCI bridge supports both host and agent configurations. As a host, it initiates transactions to PCI peripherals; as an agent, it responds to accesses from external PCI masters. Configuration is controlled via PCI_CFG[0–2] pins and internal registers, enabling flexible system topology in backplane-based communications systems.

What serial protocols are supported by the CPM in MPC8271CZQTIEA?

The CPM in MPC8271CZQTIEA supports HDLC/SDLC, UART (asynchronous/synchronous), BiSync, transparent bit-stream, QUICC multichannel (QMC), and TDM via its three SCCs and two SMCs. Each SCC can be independently configured for different protocols, and the QMC supports up to 64 time-division multiplexed channels - essential for legacy telecom interface consolidation.
