NXP Semiconductors PCF52259CAG80

Overview

PCF52259CAG80 from NXP (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for industrial connectivity and real-time control applications. It operates at up to 80 MHz, integrates 512 KB flash and 64 KB SRAM, features a Fast Ethernet controller (FEC), FlexCAN 2.0B module, USB OTG, and an 8-channel 12-bit ADC with simultaneous sampling - enabling use in networked motor control systems.

For engineers reviewing the PCF52259CAG80 datasheet, PCF52259CAG80 pinout, PCF52259CAG80 application, or PCF52259CAG80 equivalent, key selection considerations include its 144-pin LQFP package, dual watchdog timers, cryptographic acceleration unit (CAU) supporting AES/SHA-1, and Mini-FlexBus interface for external memory expansion.

Technical Context

The PCF52259CAG80 implements the ColdFire V2 core with ISA_A+ instruction set, enhanced MAC unit, and hardware divider - delivering 76 MIPS (Dhrystone 2.1) at 80 MHz. Its tightly coupled architecture supports concurrent CPU, DMA, FEC, and USB access to dual-ported SRAM.

It integrates a full-featured Fast Ethernet MAC (10/100 Mbps), FlexCAN 2.0B with 16 message buffers, and a dedicated CAU coprocessor accelerating DES, 3DES, AES, MD5, and SHA-1 - all operating under a unified clock domain with programmable PLL and low-power modes.

FAQ

What is the package type and pin count of the PCF52259CAG80?

The PCF52259CAG80 uses a 144-lead LQFP package measuring 20 mm × 20 mm with 0.5 mm lead pitch. This package provides 96 GPIO pins and full access to all integrated peripherals including FEC, FlexCAN, USB OTG, and Mini-FlexBus - unlike the 100-pin LQFP variant which omits Mini-FlexBus and reduces I/O count.

Does the PCF52259CAG80 include hardware cryptographic acceleration?

Yes, the PCF52259CAG80 integrates a Cryptographic Acceleration Unit (CAU) that offloads AES-128/256, SHA-1, MD5, DES, and 3DES operations from the CPU. This coprocessor executes cryptographic functions in fixed-cycle counts - for example, SHA-1 hash computation takes only 128 cycles - enabling secure OTA updates without degrading real-time task scheduling in PCF52259CAG80-based systems.

Can the PCF52259CAG80 operate as both a USB host and device?

Yes, the PCF52259CAG80 includes a Universal Serial Bus On-The-Go (USB OTG) controller compliant with USB 1.1 and 2.0 specifications. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) operation in both host and device modes, with 16 bidirectional endpoints and built-in transceiver - eliminating the need for external PHY components in PCF52259CAG80 USB designs.

What Ethernet capabilities does the PCF52259CAG80 support?

The PCF52259CAG80 integrates a Fast Ethernet Controller (FEC) supporting 10/100 Mbps IEEE 802.3 operation in half- or full-duplex mode. It implements the MAC layer only and requires an external PHY; supported interfaces include MII and 7-wire 10 Mbps mode. The FEC includes dedicated DMA, descriptor rings, and on-chip transmit/receive FIFOs - enabling sustained 100 Mbps throughput in PCF52259CAG80-based gateways.

Is there a real-time clock with battery backup in the PCF52259CAG80?

Yes, the PCF52259CAG80 includes a dedicated Real-Time Clock (RTC) module with 32.768 kHz crystal support and standby power supply (Vstby) input. When connected to a backup battery, the RTC maintains accurate time-of-day, alarm, and stopwatch functions during full chip stop mode - ensuring uninterrupted timekeeping in PCF52259CAG80-powered energy meters or security panels.
