Product details
Overview
R7FA0E1073CNH#BA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 32 MHz, featuring 64-KB code flash, 12-KB SRAM, a 12-bit ADC with 10 input channels, and integrated safety functions including SRAM parity check, CRC, and Independent Watchdog Timer (IWDT). It targets battery-powered industrial sensors and smart metering endpoints requiring extended runtime and functional safety compliance.
For engineers reviewing the R7FA0E1073CNH#BA0 datasheet, R7FA0E1073CNH#BA0 pinout, R7FA0E1073CNH#BA0 application, or R7FA0E1073CNH#BA0 equivalent, this page delivers verified specifications, validated 32-pin HWQFN package mapping, confirmed SAU/UARTA/IICA peripheral allocation, and two rigorously cross-referenced alternative MCUs for design flexibility in cost-sensitive, low-power embedded systems.
Technical Context
The R7FA0E1073CNH#BA0 implements the Armv8-M architecture with TrustZone®-enabled security extensions and supports dual-clock domain operation via HOCO (32 MHz), LOCO (32.768 kHz), and external crystal inputs. Its Event Link Controller (ELC) enables direct peripheral-to-peripheral triggering without CPU intervention, reducing latency and power consumption in real-time control loops.
It integrates a 32-bit interval timer (TML32) configurable as one 32-bit, two 16-bit, or four 8-bit counters, alongside eight 16-bit TAU channels supporting PWM generation and input capture. The Serial Array Unit (SAU) provides three simplified SPI, three simplified I²C, and two UART interfaces - one of which supports LIN-bus physical layer compliance.

Pinout & Package
Package: 32-pin HWQFN (PWQN0032KE-A), 5 mm × 5 mm, 0.5 mm pitch, exposed die pad (recommended electrically open).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Primary power rails; decoupling capacitor placement critical for noise immunity and stable core operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7FA0E1073CFJ | Same core, memory, and peripherals but in 32-pin LQFP (7 mm × 7 mm, 0.8 mm pitch) - larger footprint, no exposed thermal pad. | Better suited for prototyping and manual assembly; less optimal for thermally constrained PCB layouts. | Select when board reworkability or through-hole-compatible footprint is prioritized over miniaturization. |
| R7FA2E1073CNH | RA2E1-series successor with Arm Cortex-M23, same 64-KB flash/SRAM, but adds USB FS, enhanced security IP, and higher ADC sample rate (1.5 MSPS vs. 1.0 MSPS). | Required for designs needing native USB connectivity or stronger side-channel attack resistance in regulated medical or payment terminals. | Choose for new designs where future-proofing, USB integration, or advanced security certification (e.g., PSA Level 2) is mandatory. |
Compared with R7FA0E1073CFJ, the R7FA0E1073CNH#BA0 offers superior thermal dissipation and smaller PCB area via HWQFN packaging; versus R7FA2E1073CNH, it trades USB and higher-speed ADC for lower BOM cost and proven qualification in long-lifecycle industrial deployments.

FAQ
What is the maximum operating frequency of the R7FA0E1073CNH#BA0?
The R7FA0E1073CNH#BA0 operates at a maximum frequency of 32 MHz using its Arm Cortex-M23 core. This speed is achievable with the high-speed on-chip oscillator (HOCO) or an external crystal resonator. The device maintains full functionality-including ADC sampling, UART communication, and timer operations-at this frequency under all rated supply voltages (1.6–5.5 V) and temperature ranges (-40°C to +105°C). The R7FA0E1073CNH#BA0 datasheet confirms timing compliance up to 32 MHz in both normal and low-power active modes.
Does the R7FA0E1073CNH#BA0 support LIN-bus communication?
Yes, the R7FA0E1073CNH#BA0 supports LIN-bus communication through one dedicated UART channel (UART2) within its Serial Array Unit (SAU). This channel is explicitly documented in the datasheet as "UART (LIN-bus supported)" and meets ISO 17987-4 electrical and protocol requirements when paired with an external LIN transceiver. The R7FA0E1073CNH#BA0 does not integrate a LIN physical layer, so a compliant transceiver IC remains required for full bus compliance.
How many analog input channels does the R7FA0E1073CNH#BA0 ADC support?
The R7FA0E1073CNH#BA0 integrates a 12-bit successive approximation ADC (ADC12) supporting up to 10 analog input channels: AN000 through AN007, plus AN021 and AN022. These pins are mapped to dedicated physical package terminals and can be selected individually or in sequence via software configuration. The R7FA0E1073CNH#BA0 also allows internal sources-temperature sensor output and reference voltage-to be routed into the ADC for self-diagnostic or calibration purposes.
What safety features are implemented in the R7FA0E1073CNH#BA0?
The R7FA0E1073CNH#BA0 includes SRAM parity error detection, Flash Area Protection, ADC self-diagnosis, Cyclic Redundancy Check (CRC) calculation (CRC-32/CRC-CCITT), Independent Watchdog Timer (IWDT), GPIO readback level detection, register write protection, and illegal memory access detection. These features collectively support functional safety standards such as IEC 61508 SIL2. The R7FA0E1073CNH#BA0 implements them in hardware without software dependency, enabling deterministic failure response in safety-critical subsystems.
Is the R7FA0E1073CNH#BA0 pin-compatible with other RA0E1 group members?
No, the R7FA0E1073CNH#BA0 is not universally pin-compatible across the RA0E1 group. While it shares the same 32-pin HWQFN package (PWQN0032KE-A) with R7FA0E1073CFJ (LQFP), pin functions differ between package types. Within the 32-pin HWQFN variant, pin assignments are consistent across memory variants (e.g., R7FA0E1053CNH), but I/O count and analog channel availability vary. The R7FA0E1073CNH#BA0 datasheet confirms identical pinouts only for same-package, same-pin-count derivatives-not across LQFP, LSSOP, or smaller QFN variants.
