Product details
Overview
R5F1016AASP#V0 from Renesas is a 20-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller optimized for ultra-low-power embedded control in consumer-grade applications (−40°C to +85°C). It delivers 41 DMIPS at 32 MHz, operates from 1.6–5.5 V, consumes just 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates 2 KB RAM, 10-bit ADC (6 channels), UART, I²C, and 8× 16-bit timers - deployed in battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F1016AASP#V0 datasheet, R5F1016AASP#V0 pinout, R5F1016AASP#V0 application, or R5F1016AASP#V0 equivalent, key selection criteria include its 20-pin LSSOP package with 6 analog inputs, absence of on-chip data flash, support for SNOOZE/STOP/HALT low-power modes, and compatibility with Renesas' CS+ and e² studio toolchains for rapid firmware development.
Technical Context
The R5F1016AASP#V0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with 16 KB code flash organized in 1 KB blocks and 2 KB on-chip RAM.
Peripherals include a 10-bit A/D converter with internal 1.45 V reference and temperature sensor (HS mode only), dual serial interfaces (UART/LIN + I²C), up to 16 general-purpose I/O pins (including N-ch open-drain options), real-time clock with calendar/alarm, and hardware DMA controller with 2 channels - all managed under a unified low-power architecture featuring POR, LVD (14-level selectable), and multiple clock domains.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F1016AASP#V0?
The R5F1016AASP#V0 operates up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This frequency is achievable across the full 1.6–5.5 V supply range and −40°C to +85°C ambient temperature, enabling deterministic real-time control in resource-constrained applications without external clock components.
Does the R5F1016AASP#V0 include on-chip data flash memory?
No, the R5F1016AASP#V0 does not include on-chip data flash memory. It contains 16 KB of code flash and 2 KB of RAM only. This distinguishes it from the R5F1006AASP#V0 variant, which integrates 4 KB of data flash for non-volatile parameter storage - making R5F1016AASP#V0 optimal for fixed-function firmware where runtime configuration persistence is unnecessary.
Which low-power modes are supported by the R5F1016AASP#V0, and what is the lowest achievable current draw?
The R5F1016AASP#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws just 0.57 μA - verified at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on standard coin-cell batteries in always-on sensing applications.
How many analog input channels does the R5F1016AASP#V0 support, and what is the ADC resolution?
The R5F1016AASP#V0 features a 10-bit successive-approximation ADC with six dedicated analog input channels (ANI0–ANI2 plus ANI18 on P147). It includes an internal 1.45 V reference voltage and supports temperature sensing when operating in HS (high-speed main) mode - providing calibrated thermal monitoring without external components.
What development tools and IDEs are officially supported for firmware development on the R5F1016AASP#V0?
Renesas officially supports the R5F1016AASP#V0 with CS+ (formerly CubeSuite+), e² studio (Eclipse-based IDE with GCC RL78 toolchain), and IAR Embedded Workbench for RL78. Debugging is enabled via the on-chip FINE interface using E2 emulator Lite or E2 emulator, supporting full SWD-based flash programming, breakpoint setting, and real-time variable watch.
Is the R5F1016AASP#V0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F1016AASP#V0 shares identical pinout and electrical characteristics with all 20-pin LSSOP RL78/G13 variants (e.g., R5F1006AASP#V0, R5F1016CASP#V0), including identical power, ground, reset, and peripheral signal assignments. This allows direct substitution within the same package family when memory or feature requirements change - provided PCB layout accommodates the specific variant's functional constraints.
