Key Advantages

Automotive-grade reliability over extended temperature range

Large embedded Flash (1.5 MB) enables complex control software and AUTOSAR stacks

Rich analog and communication interfaces reduce external components and simplify system design

Broad voltage range (3–5.5 V) eases power supply design in vehicles and industrial environments

Mature MPC56xx platform with strong toolchain and ecosystem support

High pin count (176) and 147 I/Os allow dense, feature-rich designs

Deterministic 32-bit Power Architecture core suitable for real-time control

Packaging

Type: LQFP (Low-Profile Quad Flat Package), 176 leads

Material: epoxy molding compound; copper leadframe; lead-free matte-tin plating (RoHS3)

Size: 24 × 24 mm body, low profile; typical thickness ~1.4 mm

Pin configuration: 176 pins arranged on four sides; typical lead pitch ~0.5 mm; 147 user I/O plus power, ground, clock, reset, and interface pins (see datasheet for exact pinout)

Mounting: surface mount (SMT); tray packaging for assembly

Thermal characteristics: ambient operating -40°C to +125°C; typical thermal resistance depends on PCB; good layout and airflow recommended; junction temperature limits per datasheet

Electrical properties: supply 3.0–5.5 V; ESD and latch-up ratings per automotive standards (see datasheet); moisture sensitivity typically MSL3 for LQFP

Lifecycle

Status: Mature, widely deployed in automotive and industrial control; availability can vary by region and forecast

Not currently flagged as end-of-life, but some MPC56xx/Qorivva family parts are moving to maintenance status; new designs may consider newer families for longevity

Equivalent or alternative models:

- MPC5644A: Closest family counterpart; similar core and memory; available in high pin-count packages; check pin-for-pin and peripheral mapping

- MPC5643L: Similar architecture with smaller Flash/RAM; good for cost-optimized designs

- MPC5604B/E: Lower-end variants with reduced performance and memory; suitable when fewer features are needed

- MPC5744P (or S32 Power Architecture successors): Newer generation with higher performance and extended longevity; not pin-compatible but functionally similar for platform migration

- S32K1xx (ARM Cortex-M4): Modern automotive MCU family; not pin-compatible; consider for new designs leveraging ARM ecosystem
