Product details
Overview
R7FA2E2A33CNK#AA1 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 16-KB code flash, 8-KB SRAM, 12-bit ADC and DAC, integrated CAN interface, and hardware security including AES-128/256 and TRNG. It targets battery-powered industrial sensors and smart metering endpoints requiring functional safety and secure firmware updates.
For engineers reviewing the R7FA2E2A33CNK#AA1 datasheet, R7FA2E2A33CNK#AA1 pinout, R7FA2E2A33CNK#AA1 application, or R7FA2E2A33CNK#AA1 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, 24-pin HWQFN (4 mm × 4 mm) package with 19 GPIOs, dual watchdog timers (WDT/IWDT), ECC-protected SRAM, and I3C/SPI/SCI communication support for sensor fusion and secure edge node design.
Technical Context
The R7FA2E2A33CNK#AA1 implements Armv8-M architecture with Memory Protection Unit (MPU) supporting 8 regions, enabling robust partitioning of firmware and data in safety-critical applications. Its clock system integrates HOCO (48 MHz), MOCO (8 MHz), LOCO (32.768 kHz), and IWDT-dedicated oscillator (15 kHz), all with trim capability for precision timing across voltage and temperature.
Peripheral integration includes six 16-bit General PWM Timers (GPT16) with 10 total PWM outputs, two Low-Power Asynchronous Timers (AGTW), a 12-bit ADC with 4 selectable input channels, and dedicated analog comparator (ACMPLP) with programmable speed. The Event Link Controller (ELC) enables autonomous peripheral-to-peripheral triggering without CPU intervention, reducing active power consumption.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2E2A32DNK#AA1 | Same core, memory, and peripherals but rated for -40°C to +85°C industrial grade; 24-pin HWQFN package identical | Lower temperature range limits deployment in enclosed cabinets or high-ambient environments like solar inverters | Select when cost sensitivity outweighs extended temperature requirement and ambient stays below 85°C |
| R7FA2E2A33CNJ#AA1 | Identical electrical specs and feature set, but in 20-pin HWQFN (4 mm × 4 mm); 15 GPIOs vs. 19 on NK variant | Fewer I/O pins restrict expansion for multi-sensor configurations or complex HMI interfaces | Choose for space-constrained designs where 4 fewer GPIOs and no CAN transceiver footprint are acceptable |
Compared with R7FA2E2A33CNK#AA1, the R7FA2E2A32DNK#AA1 sacrifices extended temperature capability for lower unit cost, while R7FA2E2A33CNJ#AA1 trades I/O count and CAN support for smaller PCB area-neither offers pin compatibility, requiring layout revision for substitution.
