MPC5566 Microcontrollers Datasheet, Pinout, Specification, and Applications

The MPC5566 is a high-performance 32-bit Power Architecture microcontroller developed by NXP (formerly Freescale Semiconductor) for automotive and industrial applications. With a focus on real-time control and embedded safety, the MPC5566 microcontroller is widely used in automotive engine control, transmission control, and industrial automation systems. This article provides an in-depth overview of the MPC5566 microcontroller, covering its features, specifications, and practical applications.

Overview of MPC5566

The MPC5566 microcontroller (MCU) is part of the MPC5500 family, which integrates Power Architecture® embedded technology. This family introduces multiple innovations along with high-performance CMOS technology, delivering a notable reduction in cost per feature and a marked performance enhancement compared to the MPC500 series.

The core processor of the MPC5566 adheres to the Power Architecture embedded category and is fully compatible in user mode (including the floating-point library) with the traditional PowerPC instruction set. Additionally, this architecture introduces improvements tailored for embedded applications and extends the instruction set to include digital signal processing (DSP) capabilities.

Significant to the MPC5500 family, these enhancements are designed to offer substantial performance advancements over earlier models such as the MPC565x. The MPC5566’s processor core also features an instruction set upgrade that supports variable length encoding (VLE), which facilitates a mix of 16- and 32-bit instructions, helping to reduce the overall code footprint significantly.

The MPC5566 is structured with a two-level memory hierarchy, where the fastest access is to a 32-kilobyte (KB) unified cache. Following this are 128 KB of on-chip internal SRAM and three megabytes (MB) of internal flash memory for storing instructions and data. The external bus interface supports most standard memory types used in the MPC5xx family.

Complex input/output timer operations in the MPC5566 are managed by two enhanced time processor unit (eTPU) engines, each controlling 32 hardware channels, thus offering a total of 64 channels. Enhancements in the eTPU include 24-bit timers, multi-function channels, and expanded control and arithmetic instructions, and it is programmable using a high-level language.

For less complex timing operations, the enhanced modular input/output system (eMIOS) manages 24 hardware channels capable of various operations, including single-action, double-action, pulse-width modulation (PWM), and modulus-counter operations suitable for motor control.

Off-chip communications are facilitated through a range of serial protocols, including controller area networks (FlexCANs), enhanced de serial/serial peripheral interfaces (DSPIs), and enhanced serial communications interfaces (ASICs), with the DSPIs enhancing pin efficiency through hardware serialization.

Additionally, the MCU features an on-chip enhanced queued dual analog-to-digital converter (eQADC) with 40 channels and a system integration unit (SIU) that manages chip-wide configurations such as pad setup and external interrupts. The Fast Ethernet (FEC) module supports 10 and 100 Mbps Ethernet/IEEE® 802.3, compatible with various standard MAC PHY interfaces, and is equipped with built-in FIFOs and DMA support for enhanced data handling.
