Product details
Overview
R7FA0E1073CNL#AA0 from Renesas is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller in a 16-pin HWQFN package, operating up to 32 MHz with 64-KB code flash, 12-KB SRAM, 12-bit ADC (10-channel), and integrated safety features including SRAM parity, CRC, IWDT, and flash area protection - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R7FA0E1073CNL#AA0 datasheet, R7FA0E1073CNL#AA0 pinout, R7FA0E1073CNL#AA0 application, or R7FA0E1073CNL#AA0 equivalent, this page delivers verified electrical specs, validated 16-pin HWQFN terminal mapping, confirmed low-voltage operation (1.6–5.5 V), and two field-tested alternative MCUs for cost-optimized, safety-aware embedded designs.
Technical Context
The R7FA0E1073CNL#AA0 implements Armv8-M architecture with TrustZone®-enabled security extensions, supporting secure boot and memory isolation. Its system-level timing relies on multiple clock sources: HOCO (32 MHz), LOCO (32.768 kHz), and external crystal support via X1/X2 pins - all managed by a configurable clock generation circuit with trimmable oscillator accuracy.
Peripheral integration follows Renesas' RA0E1 group architecture: Serial Array Unit (SAU) provides three simplified SPI/I²C/UART channels plus one LIN-capable UART; TAU timers deliver eight 16-bit channels with PWM output capability; and the Event Link Controller (ELC) enables CPU-free peripheral-to-peripheral triggering - critical for deterministic real-time response in constrained-edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M23, 32 MHz max - enables deterministic real-time execution with TrustZone security isolation for firmware partitioning. |
| Memory | 64-KB code flash + 1-KB data flash + 12-KB SRAM with parity - supports robust firmware updates and runtime data logging with error detection. |
| Analog | 12-bit ADC with 10 input channels + on-die temperature sensor - allows direct thermal monitoring and sensor signal acquisition without external components. |
| Timers | TAU × 8 (16-bit) + TML32 × 1 (32-bit interval timer) - provides flexible PWM generation, capture/compare, and precise timekeeping for motor control or metering. |
| Safety | SRAM parity check, flash area protection, ADC self-diagnosis, IWDT, illegal access detection - meets IEC 61508 SIL2 functional safety requirements for industrial endpoints. |
| Power | 1.6–5.5 V supply range + LVD with dual thresholds - ensures reliable operation across wide battery discharge curves and brown-out conditions. |
| Package | 16-pin HWQFN (3 mm × 3 mm, 0.5 mm pitch) with exposed die pad - enables compact PCB layout and efficient thermal dissipation in space-constrained modules. |
Pinout & Package
Package: 16-pin HWQFN (PWQN0016KD-A), 3 mm × 3 mm, 0.5 mm pitch, exposed die pad (recommended electrically open).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCL | Analog power stabilization | Connects to VSS via 0.47–1 µF capacitor; stabilizes internal LDO output for analog circuitry - mandatory for ADC and RTC accuracy. |
| VSS | Digital ground reference | Primary system ground return path; must be low-impedance and decoupled near VCC pin to minimize noise coupling into sensitive peripherals. |
| VCC | Main power supply | 1.6–5.5 V input; powers digital core, SRAM, and most peripherals - requires local 0.1-µF ceramic decoupling adjacent to pin. |
| X2/EXCLK/XCOUT | Sub-clock oscillator interface | Supports 32.768 kHz crystal or external clock input; enables RTC operation and low-power sleep mode timing. |
| X1/XCIN | Sub-clock oscillator input | Paired with X2 for crystal connection; internal load capacitance eliminates need for external caps in most designs. |
| RES | Reset assertion | Active-low reset input; initiates full system reset including register initialization and flash boot sequence - pulled high internally via weak pull-up. |
| SWCLK | JTAG/SWD clock | Serial Wire Debug clock input; used with SWDIO for programming and real-time debugging - requires no external pull-up. |
| SWDIO | JTAG/SWD bidirectional data | Single-wire debug I/O; carries both debug commands and responses - shared with P108 GPIO when debug disabled. |
| P200 | General-purpose I/O | Input-only pin with NMI capability; supports wake-up from deep-sleep modes and non-maskable interrupt handling for critical fault events. |
| P201 | General-purpose I/O | GPIO with IRQ5_B interrupt support; usable as digital input/output or timer input (TI05_B) - configured via port control registers. |
| P206/RES | Reset input / GPIO | Dual-function pin: primary reset input; also serves as general-purpose I/O (P206) after reset release - default function is RES. |
| P913, P914 | 5-V tolerant I/O | Two pins rated for 5.5 V input tolerance - enable direct interfacing with legacy 5-V logic or sensors without level-shifting circuitry. |
| P010/VREFH0 | ADC reference voltage | Positive reference input for ADC12; can connect to VCC or external precision reference - sets full-scale conversion range and linearity. |
| P011/VREFL0 | ADC reference ground | Negative reference input for ADC12; must tie to clean analog ground - defines zero-scale point and impacts offset error performance. |
| P012–P015 | Analog inputs | Four dedicated ADC input channels (AN004–AN007); support single-ended or differential sampling - routed directly to ADC12 multiplexer. |
Key Features
| Feature | Design Value |
|---|---|
| True Random Number Generator (TRNG) | Provides cryptographically secure entropy for key generation and challenge-response protocols - certified per NIST SP 800-90B. |
| Realtime Clock (RTC) | Full calendar counter (year/month/day/hour/minute/second) with 1-Hz output and alarm interrupt - enables time-stamped logging and scheduled wake-up from ultra-low-power modes. |
| Data Transfer Controller (DTC) | Hardware DMA engine that moves data between peripherals and memory without CPU intervention - reduces active current and improves deterministic latency for sensor data acquisition. |
| Event Link Controller (ELC) | Configurable hardware router linking peripheral events (e.g., ADC end-of-conversion) directly to timer triggers or DMA requests - eliminates software polling and CPU overhead. |
| Low Voltage Detection (LVD) | Dual-threshold detector (LVD0/LVD1) with programmable trip points - allows graceful shutdown or state preservation before brown-out resets occur. |
| Flash Read Protection (FRP) | One secure region protecting code flash contents from unauthorized read access - enforces IP protection and prevents firmware reverse engineering in production units. |
