Overview
R5F1016AASM#10 from Renesas is a 20-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller with TSSOP-20 package, 1.6–5.5 V operation, 66 μA/MHz active current, and RTC+LVD standby at 0.57 μA - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1016AASM#10 datasheet, R5F1016AASM#10 pinout, R5F1016AASM#10 application, or R5F1016AASM#10 equivalent, key selection criteria include ultra-low-power HALT/STOP/SNOOZE modes, on-chip 32 MHz ±1.0% oscillator accuracy, 10-bit 6-channel ADC with internal 1.45 V reference, and UART/SPI/I²C serial interface support for embedded telemetry and actuator control.
Technical Context
The R5F1016AASM#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates DMA (2 channels), 16×16/32÷32 hardware multiplier/divider, and background data flash rewriting (BGO) with 1M-cycle endurance.
Its peripheral set includes one real-time clock with calendar/alarm/correction, one watchdog timer, eight 16-bit timers, one 12-bit interval timer, three I²C channels, two UART/LIN channels, two CSI (SPI-compatible) channels, and 16 I/O pins - all operating across –40°C to +85°C ambient temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006AASM#10 | Includes 4 KB data flash; identical package, core, and peripherals | Required when non-volatile parameter storage (e.g., calibration data) is needed alongside code | Select if field-updatable configuration persistence is mandatory |
| STM8L052C6T6 | 8-bit STM8 core; 32 KB flash, 2 KB RAM; 3.6 μA STOP mode; different peripheral register map | Lower computational throughput but proven in ultra-low-power consumer wearables | Choose for cost-sensitive designs where 16-bit math or large ISR latency is not required |
Compared with R5F1016AASM#10, R5F1006AASM#10 adds data flash at same footprint and power profile - ideal for firmware with runtime-configurable parameters; STM8L052C6T6 trades 16-bit performance for broader ecosystem tooling and lower unit cost in high-volume simple control tasks.

FAQ
What is the maximum operating frequency of the R5F1016AASM#10?
The R5F1016AASM#10 supports up to 32 MHz operation using its on-chip high-speed oscillator with ±1.0% accuracy across –20°C to +85°C. This enables 41 DMIPS performance while maintaining ultra-low active current (66 μA/MHz). The device also supports subsystem clock operation at 32.768 kHz for ultra-low-speed RTC and LVD functions - both modes are fully supported in the R5F1016AASM#10 without external components.
Does the R5F1016AASM#10 include data flash memory?
No, the R5F1016AASM#10 does not include data flash memory. Per Renesas' part numbering convention, the "101" prefix indicates data flash is omitted - confirmed in the RL78/G13 datasheet memory matrix (Page 2). This distinguishes it from the "100" series (e.g., R5F1006AASM#10), which includes 4 KB data flash. The R5F1016AASM#10 relies on SRAM or external EEPROM for non-volatile data storage.
Which serial interfaces are supported by the R5F1016AASM#10?
The R5F1016AASM#10 supports three serial interface types: two CSI (SPI-compatible) channels, two UART/LIN channels, and three I²C/Simplified I²C channels - all accessible via multiplexed pins on its 20-pin TSSOP package. Pin P10 serves SCK00/SCL00; P11 serves SI00/RxD0/TOOLRxD/SDA00. These allocations allow concurrent use of UART for debugging and I²C for sensor communication in compact designs using the R5F1016AASM#10.
What is the ADC resolution and input channel count on the R5F1016AASM#10?
The R5F1016AASM#10 features a 10-bit successive-approximation ADC with six analog input channels (ANI0–ANI2 and ANI18 among others), plus internal 1.45 V reference and temperature sensor. The ADC operates across the full 1.6–5.5 V supply range, enabling direct ratiometric measurements without external references. Channel ANI18 (P147) provides extended analog capability beyond basic ANI0–ANI2 - a verified specification in the RL78/G13 datasheet Section 1.1.
Is the R5F1016AASM#10 pin-compatible with other RL78/G13 devices in TSSOP-20?
Yes, the R5F1016AASM#10 shares identical pinout and package (20-pin TSSOP) with all other RL78/G13 20-pin variants including R5F1006AASM#10 and R5F1016CASM#10. Pin functions (e.g., P10=SCK00/SCL00, P11=SI00/RxD0/SDA00) are consistent across the family per the "Pin Configuration (Top View)" diagram (Page 13). This allows drop-in replacement for code-compatible variants differing only in flash size or data flash presence - confirmed in Renesas' official ordering part number table.
