Product details
Overview
R5F1016AASP#X0 from Renesas is a 20-pin RL78/G13 16-bit microcontroller with 16 KB flash memory, 2 KB RAM, and no data flash, designed for ultra-low-power embedded control in consumer-grade applications (–40°C to +85°C). It features a 32 MHz RL78 CPU core delivering 41 DMIPS, 6-channel 10-bit ADC, real-time clock, and multiple serial interfaces including UART, I²C, and CSI.
For engineers reviewing the R5F1016AASP#X0 datasheet, R5F1016AASP#X0 pinout, R5F1016AASP#X0 application, or R5F1016AASP#X0 equivalent, key selection criteria include its 20-pin LSSOP package, 1.6–5.5 V operation, HALT/STOP/SNOOZE low-power modes, and integrated peripherals suitable for battery-powered sensor nodes, home appliance controllers, and industrial HMI panels.
Technical Context
The R5F1016AASP#X0 implements the RL78 CISC CPU core with a 3-stage pipeline and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz), enabling dynamic performance/power trade-offs. Its memory subsystem includes 16 KB on-chip code flash (1 KB block size) and 2 KB SRAM, with no data flash-distinguishing it from R5F100x variants.
Peripherals include six 10-bit ADC input channels, one 12-bit interval timer, one real-time clock with calendar/alarm, up to four UART/LIN channels, three I²C/Simplified I²C channels, and two CSI (SPI-compatible) interfaces-all operating under single-supply 1.6–5.5 V conditions with ±1.0% oscillator accuracy across temperature.

FAQ
What is the maximum operating frequency of the R5F1016AASP#X0?
The R5F1016AASP#X0 supports a maximum CPU operating frequency of 32 MHz using the on-chip high-speed oscillator, delivering 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs at this speed, and it can scale down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs per instruction.
Does the R5F1016AASP#X0 include data flash memory?
No, the R5F1016AASP#X0 does not include data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), it provides 16 KB of code flash and 2 KB of RAM only. For data flash functionality, consider the R5F1006AASP#X0 variant, which includes 4 KB of data flash in the same 20-pin LSSOP package.
What package type and pin count does the R5F1016AASP#X0 use?
The R5F1016AASP#X0 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65-mm pitch), identified by the "SP" suffix and "#X0" embossed tape packaging code. This JEDEC-standard package supports surface-mount assembly and is compatible with standard reflow profiles for consumer-grade manufacturing.
Can the R5F1016AASP#X0 operate from a single 1.8 V supply?
Yes, the R5F1016AASP#X0 operates across a wide supply range of 1.6 V to 5.5 V, fully supporting 1.8 V nominal operation. At 1.8 V, all core functions-including 32 MHz operation, ADC, RTC, and serial interfaces-remain functional per the datasheet specifications, making it suitable for direct connection to LiFePO₄ or regulated 1.8 V rails.
What low-power modes are supported by the R5F1016AASP#X0?
The R5F1016AASP#X0 supports HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC and LVD active), and SNOOZE mode (selective peripheral wake-up while CPU remains halted). These modes are controlled via dedicated system registers and enable aggressive power optimization in intermittently active applications like remote sensors and battery-powered controls.
