Product details
Overview
R7FA2E3073CNH#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 64-KB code flash, 16-KB SRAM, a 12-bit ADC with 13 input channels, and integrated safety functions including SRAM parity, flash protection, and CAC-based clock accuracy monitoring - deployed in industrial sensor nodes requiring long battery life and functional safety compliance.
For engineers reviewing the R7FA2E3073CNH#BA0 datasheet, R7FA2E3073CNH#BA0 pinout, R7FA2E3073CNH#BA0 application, or R7FA2E3073CNH#BA0 equivalent, key selection criteria include its 32-pin HWQFN package (5 mm × 5 mm), -40°C to +105°C industrial temperature rating, 1.6–5.5 V wide supply range, dual watchdog timers (WDT/IWDT), and hardware-accelerated CRC/DOC for firmware integrity verification.
Technical Context
The R7FA2E3073CNH#BA0 implements the Armv8-M architecture with Memory Protection Unit (MPU) supporting eight regions, enabling secure partitioning of code and data memory. Its clock system integrates HOCO (48 MHz), LOCO (32.768 kHz), and SOSC for RTC, with Clock Frequency Accuracy Measurement Circuit (CAC) providing real-time oscillator drift detection against reference clocks.
Peripheral integration includes four SCI modules supporting UART, SPI, I²C, and smart card protocols; one dedicated I²C bus interface; one SPI channel; two AGT timers for low-power event counting; six GPT16 channels (7 PWM outputs); and a 32-bit GPT32 with two PWM outputs - all coordinated via Event Link Controller (ELC) to eliminate CPU intervention in time-critical signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M23, 48 MHz max - enables deterministic real-time control with TrustZone-M security extensions for firmware isolation. |
| Memory | 64-KB code flash + 2-KB data flash (100k P/E cycles) + 16-KB SRAM with parity - supports robust firmware updates and runtime data logging in field-deployed devices. |
| ADC | 12-bit successive approximation ADC with 13 selectable inputs, internal temp sensor, and reference voltage support - delivers ±1 LSB INL for precision analog sensing in environmental monitors. |
| Safety Features | SRAM parity check, flash area protection, ADC self-diagnosis, CAC, CRC calculator, DOC, IWDT - satisfies IEC 61508 SIL2 and ISO 26262 ASIL-B functional safety requirements. |
| Package & Temp | 32-pin HWQFN (5 mm × 5 mm, 0.5 mm pitch), -40°C to +105°C - suitable for compact, thermally constrained industrial enclosures without derating. |
| I/O Capability | 23 GPIOs, 15 N-ch open-drain outputs, 1 × 5-V tolerant pin (P407), pull-up resistors on all I/O - simplifies level-shifting and direct interfacing with legacy 5-V sensors and logic. |
| Power Supply | 1.6–5.5 V operation with LVD (3 threshold levels) - enables single-supply operation across battery (2×Li-ion), USB, or industrial 3.3/5 V rails without external regulators. |
Pinout & Package
Package: 32-pin HWQFN (PWQN0032KE-A), 5 mm × 5 mm body, 0.5 mm pitch, exposed thermal pad (soldered to PCB ground plane for thermal dissipation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual power domains: VCC powers digital core; AVCC0/AVSS0 required for ADC operation - decoupling with 0.1 µF capacitors per domain is mandatory. |
| P010 / P011 | VREFH0 / VREFL0 | Analog reference voltage inputs for ADC12 - must be tied to AVCC0/AVSS0 if internal reference is used; enables ratiometric measurement stability. |

| P214 / P215 | XCOUT / XCIN | Sub-clock oscillator pins - connect 32.768 kHz crystal for RTC calendar mode with automatic leap-year correction. |
| P108 / P300 | SWDIO / SWCLK | Serial Wire Debug interface - enables full JTAG-style debugging, flash programming, and real-time trace without additional pins. |
| P000–P002, P010–P015, etc. | GPIO | 23 configurable I/O pins with programmable drive strength, pull-up, and 5-V tolerance on P407 - supports mixed-voltage system interfacing and noise-immune sensor readout. |
Key Features
| Feature | Design Value |
|---|---|
| Low-Power Asynchronous Timers (AGT × 2) | 16-bit autonomous timers operable from LOCO (32.768 kHz) - enable wake-from-sleep event counting and pulse-width measurement without CPU activation, reducing active current to sub-µA levels. |
| Event Link Controller (ELC) | Hardware routing of peripheral events (e.g., ADC EOC → DTC trigger → GPT start) - eliminates interrupt latency and CPU overhead in closed-loop motor/sensor control. |
| Data Transfer Controller (DTC) | Auto-triggered DMA engine with 32-channel descriptor table - transfers ADC results to SRAM or SPI TX buffer without CPU involvement, cutting firmware execution load by >40% in data-intensive tasks. |
| Temperature Sensor (TSN) + ADC12 | On-die sensor with linear output fed directly into ADC12 - provides factory-calibrated die temperature monitoring for thermal throttling or ambient compensation in sealed enclosures. |
| Independent Watchdog Timer (IWDT) | 14-bit counter driven by dedicated 15 kHz RC oscillator - guarantees fail-safe reset even during main clock failure or software lockup, meeting ASIL-B diagnostic coverage requirements. |
Applications
| Industrial Sensor Node | Smart Meter Interface |
|---|---|
Use Scenario: Battery-powered wireless temperature/humidity node with LoRaWAN backhaul, operating unattended for 10+ years. IC Role / Device Role / Timing Role: Main controller executing sensor acquisition, CRC-protected data packaging, and low-power sleep scheduling via AGT and RTC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA2E3072DNH#BA0 | Same RA2E3 family, identical 32-pin HWQFN package and peripherals, but rated for -40°C to +85°C and 32-KB flash (vs. 64-KB). | Targeted at cost-sensitive consumer or commercial equipment where extended temperature and larger code space are unnecessary. | Select when firmware size ≤32 KB and ambient operating temperature remains below +85°C - reduces cost without sacrificing peripheral compatibility. |
| R7FA2E1073CNH#AA0 | RA2E1 series part: Cortex-M23 core, same 32-pin HWQFN, but only 128-KB flash, no CAC, reduced safety features (no DOC, limited MPU regions), and no AGT timers. | Designed for non-safety-critical general-purpose embedded control where functional safety certification is not required. | Choose for simpler applications lacking safety mandates; avoid where CAC-based clock monitoring, DOC-based data validation, or AGT-driven low-power wakeups are essential. |
Compared with R7FA2E3072DNH#BA0 and R7FA2E1073CNH#AA0, the R7FA2E3073CNH#BA0 uniquely combines industrial-grade temperature range, 64-KB flash, full safety feature set (CAC, DOC, dual WDT), and AGT timers - making it the only option among the three qualified for ASIL-B or SIL2-certified subsystems with long-term field reliability requirements.
