NXP Semiconductors MC56F82726VLF

Overview

MC56F82726VLF 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 and delivering 100 MIPS. It integrates dual 12-bit ADCs (2×8 channels), two 12-bit DACs, four analog comparators with 6-bit DAC references, one eFlexPWM module with 8 high-resolution NanoEdge PWM outputs, and supports industrial motor control (BLDC/PMSM), switched-mode power supplies, and photovoltaic systems.

For engineers reviewing the MC56F82726VLF datasheet, MC56F82726VLF pinout, MC56F82726VLF application, or MC56F82726VLF equivalent, key selection criteria include its 48-pin LQFP package, -40°C to 105°C V-temperature grade, 32 KB flash/6 KB RAM configuration, dual QSCI/QSPI interfaces, and MSCAN support - all critical for real-time embedded control in power electronics and industrial automation.

Technical Context

The MC56F82726VLF implements the 56800EX core with modified dual-Harvard architecture, enabling concurrent instruction fetches and dual data accesses per cycle. Its unified DSP/MCU architecture supports fractional arithmetic, single-cycle 32×32→64-bit MAC operations, and zero-overhead context switching via full register shadowing.

Peripherals are interconnected via dual inter-module crossbar switches supporting hardware-triggered ADC-PWM synchronization, fault-driven PWM shutdown, and configurable GPIO-to-peripheral routing. Clocking includes PLL (200–400 MHz), 8 MHz ROSC (400 kHz standby), and 200 kHz low-power oscillator - all feeding COP, EWM, and PIT modules across run/wait/stop modes.

Key Specifications

Pinout & Package

MC56F82726VLF uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are multiplexed via GPIOx_PER and SIM GPSx registers; primary reset state assigns each pin to its default peripheral role.

FAQ

What is the maximum operating frequency of the MC56F82726VLF core?

The MC56F82726VLF core operates at up to 100 MHz in fast mode, delivering 100 million instructions per second (MIPS). This frequency is achieved using the on-chip PLL with input reference clocks between 8 MHz and 16 MHz. The device also supports 50 MHz operation in normal mode, allowing dynamic power/performance scaling. All timing specifications in the MC56F827XXDS datasheet Rev. 4.1 are validated for this 100 MHz operation under -40°C to 105°C ambient conditions.

Does the MC56F82726VLF support CAN communication?

No, the MC56F82726VLF does not include the MSCAN module. According to Table 1 in the MC56F827XXDS datasheet Rev. 4.1, MSCAN is omitted in the MC56F82726VLF variant (marked "0" under MSCAN column), unlike MC56F82736VLF or MC56F82748VLH. Engineers requiring CAN must select an alternative part within the MC56F827xx family that explicitly lists MSCAN support and verify pin compatibility before redesign.

What are the memory resources allocated to the MC56F82726VLF?

The MC56F82726VLF integrates 32 KB of on-chip flash memory and 6 KB of dual-port data/program RAM. This configuration is confirmed in Table 1 of the MC56F827XXDS datasheet Rev. 4.1, where the "726VLF" row shows Flash = 32 KB and RAM = 6 KB. Both memory blocks support mapping into program and data spaces, enabling flexible code/data partitioning for real-time control tasks such as motor FOC or digital power regulation.

Which package type is used by the MC56F82726VLF?

The MC56F82726VLF uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This is explicitly stated in Table 1 of the MC56F827XXDS datasheet Rev. 4.1 under "Package pin count" for the "726VLF" variant. Pin assignments match the 48 LQFP column in Table 2 ("Signal descriptions"), confirming compatibility with standard PCB footprints for this封装 variant.

How does the MC56F82726VLF handle analog signal acquisition?

The MC56F82726VLF features two independent 12-bit cyclic ADCs, each supporting 8 external input channels with programmable x1/x2/x4 gain amplifiers. Maximum ADC clock frequency is 10 MHz (100 ns period), enabling single conversions in 10 clock cycles. ADCs synchronize with eFlexPWM events via the inter-module crossbar, ensuring precise timing for current/voltage sampling in motor control and power conversion applications - all verified in Section 1.6.2 of MC56F827XXDS Rev. 4.1.
