NXP Semiconductors MC56F82313VLC

Overview

MC56F82313VLC from NXP Semiconductors is a 32-bit digital signal controller (DSC) based on the 56800EX core, delivering 50 MIPS at 50 MHz for real-time motor control and industrial embedded applications. It integrates 16 KB flash, 4 KB RAM, dual 12-bit ADCs (5-channel each), one FlexPWM module with 6 outputs, and operates from 3.0–3.6 V across –40°C to 105°C in a 32-pin LQFP package.

For engineers reviewing the MC56F82313VLC datasheet, MC56F82313VLC pinout, MC56F82313VLC application, or MC56F82313VLC equivalent, this page delivers verified technical context, exact package mapping, validated pin functions, confirmed peripheral capabilities, and real-world selection guidance for motor control, power conversion, and smart sensor designs.

Technical Context

The MC56F82313VLC implements the 56800EX core with dual Harvard architecture, supporting concurrent instruction fetches and dual data accesses per cycle - enabling deterministic 50 MIPS execution. Its analog subsystem includes two independent 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers and hardware-triggered synchronization via crossbar to PWM or timers.

Peripheral integration centers on the FlexPWM module (6 outputs, 10 ns resolution, deadtime control) and system-level reliability features: windowed COP watchdog with multiple clock sources, external watchdog monitor (EWM), CRC generator compliant with CRC16-CCITT, and inter-module crossbar routing for ADC-PWM-timer coordination without CPU intervention.

FAQ

What is the maximum ADC sampling rate supported by the MC56F82313VLC?

The MC56F82313VLC supports a maximum ADC clock frequency of 10 MHz, enabling single conversions in 10 ADC clock cycles (1 µs) and additional conversions in 8 cycles (0.8 µs). With hardware triggering from FlexPWM, it achieves synchronized sampling rates up to 100 kSPS across both 5-channel ADCs - sufficient for three-phase current reconstruction in 20 kHz PWM systems. This specification is confirmed in Section 1.6.2 of the MC56F823XX datasheet Rev. 4.

Does the MC56F82313VLC include a hardware CRC generator, and what standard does it implement?

Yes, the MC56F82313VLC includes a dedicated hardware CRC generator compliant with CRC16-CCITT (x¹⁶ + x¹² + x⁵ + 1). It supports programmable initial seed values, bitwise transposition of input/output data, and high-speed calculation for firmware image validation or communication packet integrity. This feature is documented in Section 1.6.16 of the MC56F823XX datasheet Rev. 4 and is used in bootloader security implementations.

Can the MC56F82313VLC operate with a 5 V external interface while powered from 3.3 V?

Yes, all GPIO pins on the MC56F82313VLC (except RESETB) are 5 V–tolerant when powered from 3.0–3.6 V. This allows direct interfacing with 5 V Hall-effect sensors, optocouplers, and legacy industrial I/O without level-shifting circuitry. The RESETB pin remains strictly 3.3 V–only, requiring external clamping if exposed to 5 V signals. This behavior is specified in Section 1.3 "Operation Parameters" of the MC56F823XX datasheet Rev. 4.

What oscillator options are available for the MC56F82313VLC, and which are supported in the 32-pin LQFP package?

The MC56F82313VLC supports an 8 MHz relaxation oscillator (400 kHz in standby), a 200 kHz low-power oscillator, and an external crystal/resonator. However, the crystal oscillator is only available on MC56F82316 devices (48-pin LQFP), not on the MC56F82313VLC. Therefore, the 32-pin LQFP variant relies solely on internal oscillators - confirmed in Section 1.6.15.2 of the MC56F823XX datasheet Rev. 4.

How many PWM outputs does the MC56F82313VLC support, and what is their resolution?

The MC56F82313VLC supports six PWM outputs via its FlexPWM module, with 16-bit resolution and timing granularity as fine as 10 ns. Each output can be configured as independent or complementary pairs, with programmable deadtime insertion per pair. This capability is validated in Table 1 (MC56F823xx Family) and Section 1.6.1 of the MC56F823XX datasheet Rev. 4, enabling precise gate driving for 3-phase inverters.
