NXP Semiconductors MC56F82348MLH

Overview

MC56F82348MLH from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EX core, operating at up to 100 MHz in fast mode with 48 KB flash and 6 KB RAM. It integrates dual 12-bit ADCs (8-channel each), four analog comparators with 6-bit DAC references, two 12-bit DACs, and one eFlexPWM module supporting up to 8 high-resolution NanoEdge PWM outputs. It targets motor control (BLDC, PMSM), switched-mode power supplies, and industrial embedded systems requiring deterministic real-time processing.

For engineers reviewing the MC56F82348MLH datasheet, MC56F82348MLH pinout, MC56F82348MLH application, or MC56F82348MLH equivalent, key selection criteria include its M-temperature grade (–40°C to +125°C), 64-pin LQFP package, AEC-Q100 qualification, 5 V–tolerant I/O (except RESETB), and integrated MSCAN, QSCI, QSPI, and I²C interfaces for robust system-level connectivity.

Technical Context

The MC56F82348MLH implements the 56800EX core with modified dual-Harvard architecture-three address buses, four data buses (two 32-bit primary), and support for concurrent instruction fetches and dual data accesses per cycle. It delivers up to 100 MIPS and includes hardware MAC, bit-reverse addressing, and zero-overhead context switching via full register shadowing.

Its peripheral subsystem centers on the eFlexPWM with independent top/bottom deadtime control, synchronized submodule triggering, and FORCE_OUT event for simultaneous output updates; dual 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers and crossbar-synchronized conversion triggers; and a modular MSCAN interface compliant with CAN 2.0A/B up to 1 Mbit/s with time-stamped message buffers and listen-only mode.

Key Specifications

Pinout & Package

MC56F82348MLH is housed in a 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are multiplexed and configured post-reset via GPIOx_PER and SIM GPSx registers. Primary signals include VDD/VSS (I/O supply/ground), VDDA/VSSA (analog supply/ground), VCAP (core regulator bypass), JTAG (TCK/TMS/TDI/TDO), RESETB (active-low reset), and dedicated peripheral pins for eFlexPWM, ADC, DAC, comparators, and communication modules.

FAQ

What is the maximum operating frequency of the MC56F82348MLH core?

The MC56F82348MLH core operates at up to 100 MHz in fast mode, delivering 100 MIPS performance. This frequency is achieved using the on-chip PLL with an input reference clock of 8–16 MHz. The device also supports 50 MHz operation in normal mode. All timing specifications-including ADC conversion, PWM resolution, and communication baud rates-are validated at this 100 MHz maximum clock rate, and the MC56F82348MLH maintains full functionality across its specified –40°C to +125°C temperature range at this speed.

Does the MC56F82348MLH support CAN communication?

Yes, the MC56F82348MLH integrates a Modular/Scalable Controller Area Network (MSCAN) module compliant with CAN 2.0A/B protocol, supporting standard and extended frames, data lengths up to 8 bytes, and programmable bit rates up to 1 Mbit/s. It includes 16 message buffers with individual Rx mask registers, time-stamping for transmitted/received messages, and listen-only mode for non-intrusive bus monitoring. The MSCAN module is fully functional in the MC56F82348MLH and does not require external transceivers beyond standard CAN PHY components.

What package type and pin count does the MC56F82348MLH use?

The MC56F82348MLH is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with an exposed thermal pad. This matches the pinout of other 64-pin variants in the MC56F827xx family, such as MC56F82748MLH and MC56F82738VLH. Pin assignments-including VDD, VDDA, VCAP, RESETB, JTAG, eFlexPWM outputs, ADC inputs, and communication interface signals-are documented in Section 2 of the MC56F827XXDS datasheet and are electrically and mechanically identical across all 64-pin MLH/HLH variants.

Is the MC56F82348MLH AEC-Q100 qualified?

Yes, the MC56F82348MLH carries AEC-Q100 qualification for its M-temperature grade (–40°C to +125°C ambient). This qualification covers stress testing for accelerated environmental, thermal, and lifetime reliability per the AEC-Q100 standard, confirming suitability for automotive-adjacent applications such as engine control modules, battery management systems, and industrial equipment deployed in thermally demanding environments. The qualification status is explicitly listed in Table 1 of the MC56F827XXDS datasheet Rev. 4.1.

What are the key differences between the MC56F82348MLH and MC56F82748MLH?

The MC56F82348MLH and MC56F82748MLH share identical packaging (64-pin LQFP), temperature grade (M), core architecture (56800EX @ 100 MHz), and peripheral sets-including MSCAN, dual QSCI, dual QSPI, I²C, eFlexPWM, dual 12-bit ADCs, and four comparators. The primary difference is memory: MC56F82348MLH provides 48 KB flash and 6 KB RAM, whereas MC56F82748MLH offers 64 KB flash and 8 KB RAM. All other electrical, timing, and functional specifications are identical between the two parts.
