Product details
Overview
R5F1016AASP#50 from Renesas is a 20-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller optimized for ultra-low-power consumer applications (−40°C to +85°C), delivering 41 DMIPS at 32 MHz, 66 μA/MHz active current, and 0.57 μA RTC+LVD standby mode - deployed in battery-powered sensor nodes and smart home peripherals.
For engineers reviewing the R5F1016AASP#50 datasheet, R5F1016AASP#50 pinout, R5F1016AASP#50 application, or R5F1016AASP#50 equivalent, key selection criteria include its 20-pin LSSOP package, absence of on-chip data flash, 1.6–5.5 V supply range, integrated 10-bit ADC with 6 channels, and support for HALT/STOP/SNOOZE low-power modes.
Technical Context
The R5F1016AASP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 16-bit timer (8 channels), real-time clock with calendar/alarm, and 10-bit A/D converter with internal 1.45 V reference and temperature sensor.
Its memory subsystem includes 16 KB code flash (1 KB block size), 2 KB RAM, and no data flash - distinguishing it from R5F100x variants. Power management features include on-chip POR, 14-level LVD, and dedicated low-speed oscillator for watchdog operation independent of main clock.

FAQ
Does R5F1016AASP#50 include on-chip data flash memory?
No, R5F1016AASP#50 does not include data flash memory. It contains 16 KB of code flash and 2 KB of RAM only. This distinguishes it from R5F100x variants (e.g., R5F1006AASP#50), which integrate 4 KB of data flash for non-volatile parameter storage. The R5F1016AASP#50 is optimized for applications where firmware-only storage suffices.
What package type and pin count does R5F1016AASP#50 use?
R5F1016AASP#50 uses a 20-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), designated by the "SP" suffix and #50 embossed tape packaging specification. It is JEDEC MO-153 compliant and compatible with standard SMT reflow processes. Pin configuration matches other 20-pin RL78/G13 devices including shared analog and interrupt-capable I/O.
Can R5F1016AASP#50 operate from a single 1.8 V supply?
Yes, R5F1016AASP#50 supports operation from 1.6 V to 5.5 V, making it fully functional at 1.8 V. At this voltage, the maximum operating frequency is reduced per datasheet specifications, but all peripherals-including the 10-bit ADC, RTC, and low-power modes-remain operational. This enables direct interfacing with 1.8 V logic and sensors without level-shifting.
How many analog input channels does R5F1016AASP#50 support?
R5F1016AASP#50 supports six analog input channels: ANI0 through ANI2 on P20–P22, plus ANI18 on P147, and two additional channels accessible via alternate functions on other pins (e.g., AVREFP/AVREFM). All channels are routed to the same 10-bit successive-approximation ADC with internal 1.45 V reference and temperature sensor capability.
Is R5F1016AASP#50 pin-compatible with R5F1006AASP#50?
Yes, R5F1016AASP#50 is pin-compatible with R5F1006AASP#50 - both use identical 20-pin LSSOP packages and share identical pin functions, electrical characteristics, and footprint. The sole functional difference is the absence of data flash in R5F1016AASP#50, making it a drop-in replacement where data logging is not required.
