Product details
Overview
R5F1016DASM#50 from Renesas is a 20-pin, 32 KB flash, 2 KB RAM RL78/G13 16-bit microcontroller with no data flash, designed for ultra-low-power industrial applications (–40°C to +85°C). It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates 10-bit ADC (6 channels), UART, I²C, SPI, 16-bit timers, and real-time clock.
For engineers reviewing the R5F1016DASM#50 datasheet, R5F1016DASM#50 pinout, R5F1016DASM#50 application, or R5F1016DASM#50 equivalent, key selection criteria include its TSSOP-20 package, absence of data flash, industrial temperature rating, low-power HALT/STOP/SNOOZE modes, and integrated analog peripherals for sensor interfacing and control-loop execution.
Technical Context
The R5F1016DASM#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with on-chip resources including 32 KB code flash (1 KB block size), 2 KB RAM, and no data flash - confirmed by the "101" prefix in the part number denoting data flash omission.
It features a high-accuracy ±1.0% on-chip oscillator (32 MHz max), 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and peripheral sets including UART/LIN, I²C, CSI (SPI-compatible), up to 16× 16-bit timers, RTC with calendar/alarm, and watchdog timer - all operating across 1.6–5.5 V supply and –40°C to +85°C ambient range.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F1016DASM#50?
The R5F1016DASM#50 operates at up to 32 MHz, delivering 41 DMIPS of processing performance. This speed is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C. The R5F1016DASM#50 sustains this performance while consuming only 66 μA per MHz, making it suitable for real-time control loops in battery-powered equipment.
Does the R5F1016DASM#50 include data flash memory?
No, the R5F1016DASM#50 does not include data flash memory. The "101" in its part number explicitly indicates data flash omission, confirmed in Renesas documentation. It provides 32 KB of code flash and 2 KB of RAM only. For applications requiring non-volatile parameter storage, external EEPROM or the R5F1006DASM#50 (which includes 4 KB data flash) should be considered.
What are the supported low-power modes and their typical current consumption for the R5F1016DASM#50?
The R5F1016DASM#50 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws 0.57 μA - enabling multi-year operation on a CR2032 coin cell. HALT mode consumes approximately 1.2 μA with main clock stopped but RAM retained, while SNOOZE allows selected peripherals to operate during CPU sleep. All modes retain full register and RAM state.
Which communication interfaces are available on the R5F1016DASM#50, and how are they mapped to pins?
The R5F1016DASM#50 integrates UART, I²C, and CSI (SPI-compatible) interfaces. Pins P10, P11, and P12 share SCK/SCL, SI/RxD/SDA, and SO/TxD/SDA functions respectively - enabling flexible protocol assignment. UART supports LIN bus physical layer compliance. No external transceivers are needed for basic point-to-point communication, though level-shifting may be required for 3.3 V ↔ 5 V interoperation.
What is the analog capability of the R5F1016DASM#50, and does it include a temperature sensor?
The R5F1016DASM#50 features a 10-bit A/D converter with 6 analog input channels (including ANI0–ANI2 and ANI18), internal 1.45 V reference voltage, and an integrated factory-calibrated temperature sensor. The sensor output is accessible via a dedicated ADC channel and requires no external components - enabling accurate thermal monitoring in thermostats, power supplies, or motor drives without added BOM cost.
