Product details
Overview
R5F1016DASP#50 from Renesas is a 20-pin, 32 KB flash, 2 KB RAM RL78/G13 16-bit microcontroller with data flash disabled, industrial-grade (–40°C to +85°C) operation, ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrated 10-bit ADC (26-channel), UART, I²C, and 16-bit timers - deployed in battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F1016DASP#50 datasheet, R5F1016DASP#50 pinout, R5F1016DASP#50 application, or R5F1016DASP#50 equivalent, key selection criteria include its LSSOP-20 package, absence of on-chip data flash, industrial temperature rating, and support for background data flash programming in compatible variants.
Technical Context
The R5F1016DASP#50 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and DMA controller with 2 channels.
Its peripheral set includes up to 26 analog inputs for the 10-bit A/D converter, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels - all configurable via register-based control without external glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1016EASP#50 | Same package and core, but includes 4 KB data flash and supports background operation (BGO) and flash library functions | Required for field-upgradable firmware or nonvolatile parameter storage without external EEPROM | Select when persistent configuration storage or bootloader self-update capability is needed |
| R5F1006DASP#50 | Identical LSSOP-20 package and 32 KB flash, but includes 4 KB data flash and operates at consumer temp range (–40°C to +85°C, grade A) | Suitable for cost-sensitive commercial products where industrial temp rating is not mandatory | Choose for consumer-grade applications where data flash is required and extended temperature qualification is unnecessary |
Compared with R5F1016DASP#50, R5F1016EASP#50 adds data flash for runtime parameter retention and firmware updates, while R5F1006DASP#50 trades industrial qualification for data flash - making R5F1016DASP#50 optimal for space-constrained, battery-powered industrial controls where flash simplicity and guaranteed temp performance outweigh data persistence needs.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F1016DASP#50?
The R5F1016DASP#50 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, active-mode current is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripheral activity. In STOP mode with only RTC and LVD enabled, it draws just 0.57 μA, enabling multi-year battery operation in always-on sensing applications.
Does the R5F1016DASP#50 include on-chip data flash memory?
No, the R5F1016DASP#50 does not include on-chip data flash memory. The "1" in the second digit of the part number (R5F1016DASP#50) explicitly indicates data flash is omitted. This distinguishes it from R5F1006DASP#50 (which has 4 KB data flash) and affects use cases requiring nonvolatile parameter storage or background flash programming.
Which package type and pin count does the R5F1016DASP#50 use?
The R5F1016DASP#50 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65 mm pitch), designated by the "SP" suffix and confirmed in Renesas' ordering guide. It provides 16 general-purpose I/O pins, including analog inputs, UART, I²C, and SPI-capable signals - optimized for compact industrial control modules.
What are the supported operating temperature ranges for the R5F1016DASP#50?
The R5F1016DASP#50 is rated for industrial operation from –40°C to +85°C, indicated by the "D" suffix in the part number. This qualifies it for deployment in harsh environments such as factory automation controllers, outdoor utility meters, and HVAC systems - unlike consumer-grade "A" variants limited to the same ambient range but without industrial qualification testing.
Can the R5F1016DASP#50 execute code while writing to flash memory?
No - because the R5F1016DASP#50 lacks on-chip data flash, it does not support background operation (BGO) or flash self-programming during code execution. Code flash writes require CPU suspension. For applications needing concurrent execution and flash updates, consider R5F1016EASP#50 (which includes 4 KB data flash and BGO capability).
