Product details
Overview
MCF5407AI162 from Motorola (now NXP Semiconductors) is a ColdFire® v2 32-bit microprocessor with integrated system-level peripherals, designed for embedded control and communications applications. It features a 162 MHz CPU clock (via PLL), 16 KB instruction cache + 8 KB data cache, on-chip 2 KB SRAM, I²C, UARTs, DMA, DRAM controller, and IEEE 1149.1 JTAG debug support - deployed in industrial gateways and protocol-conversion edge devices.
For engineers reviewing the MCF5407AI162 datasheet, MCF5407AI162 pinout, MCF5407AI162 application, or MCF5407AI162 equivalent, key selection considerations include its ColdFire v2 core architecture, PLL-configurable clocking up to 162 MHz, integrated SIM peripheral set, external bus interface timing, and BDM-based real-time debug capability.
Technical Context
The MCF5407AI162 implements the ColdFire v2 instruction set architecture with dual-pipeline Harvard execution (IFP/OEP), hardware MAC and integer divide units, and configurable cache coherency modes (write-through/copyback). Its System Integration Module (SIM) provides centralized control of PLL, interrupt routing, chip selects, and watchdog functions.
It supports synchronous/asynchronous DRAM via dedicated controller, includes four UART modules with FIFOs, two I²C interfaces, a 16-bit parallel port, and programmable timers - all mapped into a unified memory space with MBAR-based peripheral register addressing and ACR-controlled access protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ColdFire v2 32-bit RISC core with dual pipelines (IFP/OEP), no MMU - enables deterministic real-time execution without virtual memory overhead. |
| Max CPU Frequency | 162 MHz (PLL-derived from 33.33 MHz crystal) - delivers ~160 MIPS performance for protocol stack and control-loop processing. |
| Cache | 16 KB instruction cache + 8 KB data cache, configurable write-through or copyback - reduces external memory bandwidth demand in burst-access scenarios. |
| On-Chip Memory | 2 KB SRAM (dual-banked), accessible as fast local RAM or cacheable data storage - used for critical buffers, stack, or ISR context preservation. |
| I²C Interface | Dual I²C modules supporting standard/fast-mode (up to 400 kHz), slave/master operation, and arbitration - enables sensor hub and PMIC communication without external bridge ICs. |
| Debug Interface | IEEE 1149.1 JTAG TAP + Background Debug Mode (BDM) with PSTDDATA trace - allows non-intrusive real-time instruction tracing and breakpoint debugging in production firmware. |

Pinout & Package
The MCF5407AI162 is housed in a 256-pin PQFP (Plastic Quad Flat Package) with 0.65 mm pitch, measuring 28 × 28 mm. Pin assignments follow Motorola's standardized ColdFire pinout layout for signal grouping (address/data multiplexing, peripheral I/O, clock, reset, and JTAG).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Reference Clock Input | Accepts 33.33 MHz crystal or oscillator input to PLL - determines base frequency for all internal clocks including PCLK, BCLKO, and PSTCLK. |
| RSTI | Asynchronous Reset Input | Active-low asynchronous reset that clears CPU state, resets PLL, and initializes SIM registers - requires external pull-up and debouncing for reliable power-on reset. |
| TCK/TMS/TDI/TDO | JTAG Test Access Port | IEEE 1149.1-compliant boundary-scan and debug interface - enables programming, emulation, and structural testing without dedicated debug headers. |
| CS0–CS9 | Chip Select Outputs | 10 independent active-low chip select signals with programmable timing - each maps to a distinct memory or peripheral address range defined in SIM CSBAR registers. |
| DS/AS/RW | Bus Control Signals | Data Strobe, Address Strobe, and Read/Write control - coordinate multiplexed address/data transfers on the external bus per Motorola 68K-compatible timing protocol. |
| TXD0/RXD0 | UART0 Serial Interface | Transmit and receive data lines for primary UART channel - supports RS-232/RS-485 level-shifting and hardware flow control via CTS/RTS pins. |
Key Features

FAQ
What is the maximum operating frequency of the MCF5407AI162?
The MCF5407AI162 operates at a maximum CPU frequency of 162 MHz, achieved by configuring its on-chip PLL to multiply a 33.33 MHz crystal input. This frequency is specified under industrial temperature range (–40°C to +85°C) and 3.3 V ±0.3 V supply conditions. The MCF5407AI162 datasheet confirms this rating in Section 7.1 (PLL:PCLK Ratios) and Electrical Specifications tables.
Does the MCF5407AI162 include an integrated memory management unit (MMU)?
No, the MCF5407AI162 does not include an MMU. It implements the ColdFire v2 architecture with a Memory Protection Unit (MPU)-like access control via four Access Control Registers (ACR0–ACR3), enabling region-based read/write/execute permissions but not virtual memory translation. This design targets real-time deterministic applications where MMU overhead is unnecessary - a confirmed feature in Chapter 4 and Section 4.10.2 of the MCF5407AI162 User's Manual.
How many UART modules does the MCF5407AI162 support?
The MCF5407AI162 integrates four independent UART modules, each with programmable baud rate, FIFO buffering, and modem control signaling (CTS/RTS/DSR/DTR). These are documented in Section 1.3.5 and Chapter 13 of the MCF5407AI162 User's Manual, and support simultaneous RS-232, RS-485, and legacy serial device interfacing without external UART expanders.
What debug interfaces are supported by the MCF5407AI162?
The MCF5407AI162 supports both IEEE 1149.1 JTAG for boundary scan and structural test, and Background Debug Mode (BDM) via a 6-pin serial interface for real-time code download, breakpoint insertion, and instruction trace using PSTDDATA[7:0]. This dual-mode debug capability is detailed in Chapters 5 and 16 of the MCF5407AI162 User's Manual and enables both pre-silicon validation and field firmware updates.
Is the MCF5407AI162 pin-compatible with other ColdFire processors like the MCF5206 or MCF5307?
No, the MCF5407AI162 is not pin-compatible with MCF5206 or MCF5307 devices. It uses a 256-pin PQFP package with a unique pinout optimized for its expanded peripheral set (dual I²C, DRAM controller, 10 chip-selects), whereas MCF5206 uses 160-pin QFP and MCF5307 uses 208-pin PQFP. Pin mapping differences are confirmed in the Mechanical Data appendix and Signal Descriptions chapter of the MCF5407AI162 documentation.
