NXP Semiconductors MC56F82723VLC

Overview

MC56F82723VLC 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 32 KB flash and 6 KB RAM. It integrates dual 12-bit ADCs (2×3 channels), three analog comparators, one 12-bit DAC, and an eFlexPWM module with six 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 MC56F82723VLC datasheet, MC56F82723VLC pinout, MC56F82723VLC application, or MC56F82723VLC equivalent, key selection criteria include its 32-pin LQFP package, V-temp grade (–40°C to 105°C), 3.3 V single supply, 5 V–tolerant I/O (excluding RESETB), and support for QSCI, QSPI, I²C, and crossbar-based peripheral synchronization.

Technical Context

The MC56F82723VLC implements the 56800EX core with dual Harvard architecture, enabling concurrent instruction fetch and dual data accesses per cycle. Its eFlexPWM submodule supports six high-resolution PWM outputs with independent deadtime, polarity, and FORCE_OUT synchronization - critical for precise gate drive timing in three-phase motor inverters.

Analog subsystem integration includes two 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers and synchronized triggering via crossbar-linked PWM events. The device uses a 32-pin LQFP package with dedicated VDDA/VSSA pins, separate VCAP regulation, and JTAG/EOnCE debug interface routed to TDI/TDO/TCK/TMS pins.

FAQ

What is the maximum operating frequency of the MC56F82723VLC core?

The MC56F82723VLC core operates at up to 100 MHz in fast mode, delivering 100 MIPS performance. This frequency is achieved using the internal PLL with an 8–16 MHz crystal input. The device also supports 50 MHz operation in normal mode. All timing specifications in the MC56F827XXDS datasheet Rev. 4.1 are validated at this 100 MHz maximum, and the MC56F82723VLC maintains full peripheral functionality across its rated temperature range of –40°C to 105°C.

Does the MC56F82723VLC support CAN communication?

No, the MC56F82723VLC does not include a Controller Area Network (CAN) module. According to Table 1 in MC56F827XXDS Rev. 4.1, MSCAN is explicitly omitted from all MC56F8272x variants, including MC56F82723VLC and MC56F82723VFM. CAN capability is only present in higher-tier members like MC56F82748VLH and MC56F82738VLH. For MC56F82723VLC, communication is limited to QSCI, QSPI, and I²C/SMBus interfaces.

What are the analog input capabilities of the MC56F82723VLC?

The MC56F82723VLC features two independent 12-bit cyclic ADCs, each supporting three external analog inputs (totaling six channels), with programmable x1/x2/x4 gain amplifiers. It also includes three analog comparators, each with a 6-bit DAC reference and selectable hysteresis. These resources are sufficient for three-phase current sensing with hardware-synchronized sampling and overcurrent protection - confirmed in the "MC56F827xx Family" comparison table and Section 1.6.2 of MC56F827XXDS Rev. 4.1.

Is the MC56F82723VLC pin-compatible with other MC56F827xx devices in the same package?

Yes, the MC56F82723VLC is pin-compatible with all other MC56F827xx variants offered in the 32-pin LQFP package, including MC56F82733VLC and MC56F82723VFM (though VFM is QFN). Signal mapping, power pin locations (VDD/VSS/VDDA/VSSA/VCAP), and JTAG interface pins (TDI/TDO/TCK/TMS) are identical across these 32-pin LQFP variants, enabling drop-in replacement for memory/peripheral upgrades without PCB redesign - as verified in Table 2 and Section 11 of MC56F827XXDS Rev. 4.1.

What debug interface does the MC56F82723VLC provide?

The MC56F82723VLC provides a JTAG interface compliant with IEEE 1149.1, supporting enhanced on-chip emulation (EOnCE) for unobtrusive, real-time debugging independent of CPU speed. Pins TDI (32), TDO (30), TCK (1), and TMS (31) are dedicated to this function, with internal pullup/pulldown resistors enabled at reset. External 2.2 kΩ pullup on TMS is recommended to retain debug capability - details are specified in Section 2 and Table 2 of MC56F827XXDS Rev. 4.1.
