NXP Semiconductors MPC8270CZQMIBA

Overview

MPC8270CZQMIBA 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 one Multichannel Controller (MCC). It operates at up to 450 MHz and targets embedded networking, industrial gateways, and telecom edge equipment.

For engineers reviewing the MPC8270CZQMIBA datasheet, MPC8270CZQMIBA pinout, MPC8270CZQMIBA application, or MPC8270CZQMIBA 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 10/100 Ethernet via MII/RMII, and absence of UTOPIA II and TC-layer hardware-distinguishing it from MPC8280.

Technical Context

The MPC8270CZQMIBA integrates a Power Architecture-compliant G2_LE microprocessor core with separate 16 KB instruction and data caches, physically addressed and four-way set associative. Its Communications Processor Module (CPM) includes a 32-bit RISC coprocessor, 32 KB dual-port instruction RAM, 32 KB dual-port data RAM, and dedicated serial DMA channels for FCCs, SCCs, and SMCs.

It supports three FCCs for 10/100-Mbit Ethernet (MII/RMII), HDLC, transparent, and ATM protocols (excluding SAR on MPC8270), plus four SCCs compatible with UART, HDLC, SDLC, BISYNC, and synchronous UART. Unlike the MPC8280, it lacks UTOPIA II ports, TC layer, IMA, and second MCC-confirmed in Table 1 and Figure 1 notes.

FAQ

What is the maximum operating frequency of the MPC8270CZQMIBA core?

The MPC8270CZQMIBA supports a maximum core frequency of 450 MHz, achieved via 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, Tj ≤ 105°C) and enables high-throughput packet processing in routing and bridging applications. The actual achievable speed depends on thermal design and voltage stability - MPC8270CZQMIBA must maintain junction temperature below 105°C for sustained 450 MHz operation.

Does the MPC8270CZQMIBA support UTOPIA II interfaces?

No, the MPC8270CZQMIBA does not support UTOPIA II interfaces. This capability is explicitly reserved for the MPC8280 variant, as confirmed in Table 1 (Functionality) and Figure 1 notes of the MPC8280EC hardware specification. The MPC8270CZQMIBA implements three FCCs for 10/100 Ethernet, HDLC, and transparent protocols but omits UTOPIA II ports, TC layer, and IMA - making it unsuitable for ATM SAR applications requiring UTOPIA physical layer connectivity.

What package type is used for the MPC8270CZQMIBA?

The MPC8270CZQMIBA uses a 480-ball TBGA (Thin Ball Grid Array) package, lead-free, with 27 mm × 27 mm footprint and 1.0 mm ball pitch. This corresponds to the "ZU" (leaded) or "VV" (lead-free) package codes defined in Table 2 of the MPC8280EC document. The "CZQMIBA" suffix confirms the VV variant - a RoHS-compliant, Pb-free assembly suitable for modern industrial PCB assembly processes.

How many serial communication controllers (SCCs) does the MPC8270CZQMIBA include?

The MPC8270CZQMIBA includes four serial communications controllers (SCCs), identical in function to those on the MPC860. Each SCC supports multiple protocols including Ethernet/IEEE 802.3, HDLC/SDLC, UART, synchronous UART, BISYNC, and transparent modes. These are implemented on CPM pins PA[0–31], PB[4–31], PC[0–31], and PD[4–31], and are fully configurable via CPM microcode - enabling flexible serial interface deployment in protocol gateway applications.

Is the MPC8270CZQMIBA pin-compatible with the MPC8280?

No, the MPC8270CZQMIBA is not pin-compatible with the MPC8280. While both share the 480-ball TBGA package option (ZU/VV), the MPC8280 is also offered in 516-ball PBGA (VR/ZQ) packages and includes additional signals for UTOPIA II, TC layer, and second MCC - requiring different pin assignments. Table 2 confirms MPC8270 is listed for ZU/VV only, whereas MPC8280 appears in all four packages. Signal-level incompatibility and differing pin functions preclude direct PCB substitution.
