NXP Semiconductors KMPC8270CZUUPEA

Overview

KMPC8270CZUUPEA from Freescale Semiconductor is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core, 16 KB instruction and 16 KB data caches, three Fast Communication Controllers (FCCs), four Serial Communications Controllers (SCCs), and PCI bridge functionality - all in a 480-pin TBGA package with leaded finish. It targets embedded networking applications including industrial gateways, TDM-based voice/data multiplexers, and legacy telecom infrastructure requiring deterministic real-time packet processing at up to 450 MHz CPU frequency.

For engineers reviewing the KMPC8270CZUUPEA datasheet, KMPC8270CZUUPEA pinout, KMPC8270CZUUPEA application, or KMPC8270CZUUPEA equivalent, key selection considerations include its 480 TBGA (ZU) package compatibility, absence of UTOPIA II and TC layer hardware (unlike MPC8280), single multichannel controller (MCC1), and support for up to eight TDM interfaces via one SI block - critical for time-sensitive serial interface consolidation in space-constrained designs.

Technical Context

The KMPC8270CZUUPEA integrates a Power Architecture–compliant G2_LE core with separate PLLs for core and CPM domains, enabling independent clock scaling (e.g., 450 MHz core / 233 MHz CPM). Its Communication Processor Module (CPM) includes a 32-bit RISC microcontroller, 32 KB dual-port RAM, and dedicated DMA channels for FCC/SCC/TDM traffic - offloading protocol handling from the main CPU.

It supports 32-bit local bus (up to 100 MHz), 64-bit 60x bus (up to 133 MHz effective), and PCI 2.2-compliant bridge (66 MHz, 3.3 V) with four DMA channels. Unlike MPC8280, it lacks UTOPIA II ports, TC layer, IMA, and second MCC - confirming its role as a cost-optimized variant within the HiP7 PowerQUICC II family for non-ATM, non-high-density TDM applications.

Key Specifications

Pinout & Package

KMPC8270CZUUPEA is housed in a 480-ball thin BGA (TBGA) package with leaded finish (ZU code), measuring 27 mm × 27 mm × 1.7 mm (body height), ball pitch 1.27 mm, and JEDEC MO-205AC compliant footprint. The package supports standard reflow profiles and provides thermal dissipation via solder balls to PCB ground plane.

FAQ

What is the maximum CPU frequency supported by KMPC8270CZUUPEA?

KMPC8270CZUUPEA supports a maximum CPU frequency of 450 MHz, achieved using an internal core clock multiplier ratio of 8:1 with a 56.25 MHz CLKIN source. This frequency is validated under recommended operating conditions (VDD = 1.45–1.60 V, TA = 0–70 °C) and requires proper thermal management to maintain junction temperature ≤105 °C.

Does KMPC8270CZUUPEA include UTOPIA II interface hardware?

No, KMPC8270CZUUPEA does not include UTOPIA II interface hardware. As confirmed in Table 1 and Figure 1 notes of the MPC8280EC document, UTOPIA II ports are exclusive to MPC8280 and MPC8275 variants. KMPC8270CZUUPEA supports only FCC-based Ethernet and SCC-based HDLC/transparent protocols - making it unsuitable for ATM SAR implementations.

What package type and ball count does KMPC8270CZUUPEA use?

KMPC8270CZUUPEA uses a 480-ball thin BGA (TBGA) package with leaded finish, designated by the ZU code per Table 2 of the MPC8280EC datasheet. Its mechanical dimensions are 27 mm × 27 mm × 1.7 mm, with 1.27 mm ball pitch and JEDEC MO-205AC compliance - distinct from the 516-ball VR/ZQ packages used by MPC8275/MPC8280.

How many TDM interfaces does KMPC8270CZUUPEA support?

KMPC8270CZUUPEA supports up to eight TDM interfaces through its single Serial Interface (SI) block (TDM2[A–D]), as explicitly stated in Figure 1 notes and Table 1. This differs from MPC8280's dual SI blocks (eight TDMs total) and reflects KMPC8270CZUUPEA's targeted use in mid-density voice/data multiplexing rather than full-scale telecom line cards.

Is KMPC8270CZUUPEA pin-compatible with MPC8280CZVPEA?

KMPC8270CZUUPEA and MPC8280CZVPEA share the same ZU (480 TBGA) package code and pinout, as confirmed in Table 2 and Section 1 overview of MPC8280EC. However, functional differences - such as absence of UTOPIA II, TC layer, and IMA in KMPC8270CZUUPEA - mean that direct replacement requires firmware and hardware validation despite identical physical layout.
