NXP Semiconductors MC56F80736VLF

Overview

MC56F80736VLF from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EF core, operating at up to 100 MHz with 48 KB flash and 8 KB RAM. It integrates dual 12-bit ADCs with x1/x2/x4 programmable gain amplifiers, three analog comparators with 8-bit DAC references, and an eFlexPWM module supporting up to 8 channels with 312 ps NanoEdge resolution. It targets industrial motor control, solar inverters, and UPS systems requiring real-time signal processing and precise PWM timing.

For engineers reviewing the MC56F80736VLF datasheet, MC56F80736VLF pinout, MC56F80736VLF application, or MC56F80736VLF equivalent, key selection criteria include its V-grade temperature range (–40°C to +105°C), 64-pin LQFP package, 2.7–3.6 V single-supply operation, and support for LIN slave, QSPI, and LPI2C interfaces in safety-critical embedded control designs.

Technical Context

The MC56F80736VLF implements the 56800EF core with unified DSP/MCU architecture, including an enhanced FPU compliant with IEEE 754-2008 and a CORDIC engine for trigonometric/hyperbolic computation. Its memory map supports flexible allocation of flash and RAM across program and data spaces.

Peripheral integration centers on deterministic real-time control: the eFlexPWM module enables sub-nanosecond edge placement via NanoEdge, while dual ADCs synchronize with PWM triggers for closed-loop current sensing. The inter-module crossbar routes signals between ADCs, comparators, timers, and PWMs without CPU intervention.

FAQ

What is the maximum operating frequency of the MC56F80736VLF core?

The MC56F80736VLF features a 32-bit 56800EF core rated for up to 100 MHz operation, delivering 100 MIPS performance. This frequency is achievable under the specified 2.7–3.6 V supply and –40°C to +105°C ambient conditions. The core uses an internal PLL with input reference from 8–16 MHz crystal or IRC sources, and its timing is validated per NXP's MC56F80XXX Rev. 2.1 datasheet section 1.2 and Table 1.

Does the MC56F80736VLF support LIN bus communication?

Yes, the MC56F80736VLF supports LIN slave functionality through its two queued serial communication interface (QSCI) modules. Each QSCI includes hardware support for LIN protocol framing, wakeup detection (idle line and address mark), and 1/16 bit-time noise filtering. This capability is documented in section 1.5.9 of the MC56F80XXX datasheet and enables direct integration into automotive body control modules or industrial sensor networks.

How many analog-to-digital converter channels does the MC56F80736VLF have?

The MC56F80736VLF integrates two independent 12-bit cyclic ADCs: ADCA and ADCB. Each supports 14 external input channels, programmable gain (x1/x2/x4), and simultaneous sampling modes. Total usable analog input count is 28 channels, with hardware-triggered synchronization to PWM and timer events. This configuration is confirmed in Table 1 (MC56F80xxx Family) and section 1.5.2 of the official datasheet.

What package type and pin count does the MC56F80736VLF use?

The MC56F80736VLF is supplied in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This matches the "64 LQFP" entry for the MC56F80736 variant in Table 1 of the MC56F80XXX datasheet. Pin assignments-including VDD, VDDA, VCAP, ADC inputs, PWM outputs, and communication interfaces-are fully detailed in sections 2 and 4 of the datasheet.

Is the MC56F80736VLF qualified for industrial temperature operation?

Yes, the MC56F80736VLF carries the "V grade" qualification, specifying operation from –40°C to +105°C ambient temperature. This rating is explicitly stated in section 1.3 (Operation Parameters) and Table 1 of the MC56F80XXX datasheet. It meets industrial requirements for enclosed motor drives, UPS systems, and solar inverters where sustained high-temperature operation is mandatory.
