Product details
Overview
R5F1016DASM#70 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#70 datasheet, R5F1016DASM#70 pinout, R5F1016DASM#70 application, or R5F1016DASM#70 equivalent, key selection considerations include its TSSOP-20 package, industrial temperature grade (D-suffix), absence of data flash, 1.6–5.5 V operation, and support for SNOOZE/STOP/HALT low-power modes in battery-powered sensor nodes and smart actuators.
Technical Context
The R5F1016DASM#70 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space, with on-chip resources including 32 KB code flash, 2 KB RAM, and peripheral blocks tightly coupled via an internal bus matrix.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, while timing relies on a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC. The device supports background operation during data flash rewriting-though not applicable here, as R5F1016DASM#70 lacks data flash per family designation.

FAQ
What is the maximum operating frequency and performance of the R5F1016DASM#70?
The R5F1016DASM#70 operates at up to 32 MHz and delivers 41 DMIPS of processing performance. This is achieved using the RL78 CPU core with a 3-stage pipeline and high-speed on-chip oscillator. Its minimum instruction execution time is 0.03125 μs at 32 MHz, making it suitable for real-time control tasks such as motor commutation or sensor fusion in the R5F1016DASM#70-based design.
Does the R5F1016DASM#70 include data flash memory?
No, the R5F1016DASM#70 does not include data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 documentation), this variant provides only code flash (32 KB) and on-chip RAM (2 KB), with no dedicated data flash block. For applications requiring nonvolatile parameter storage, consider R5F1006DASM#70 (4 KB data flash) or external EEPROM - both supported in the R5F1016DASM#70 hardware design.
What low-power modes are supported by the R5F1016DASM#70?
The R5F1016DASM#70 supports HALT, STOP, and SNOOZE modes. In HALT mode with only RTC and LVD active, current consumption is 0.57 μA typical. STOP mode reduces current further depending on enabled wake-up sources, and SNOOZE allows selected peripherals (e.g., UART, ADC) to operate while CPU remains halted. These modes are fully accessible via the R5F1016DASM#70's power control registers and require no external components.
Which communication interfaces are available on the R5F1016DASM#70?
The R5F1016DASM#70 integrates UART (with LIN bus support), I²C, and CSI (a Renesas SPI-compatible interface), all configurable on shared pins P10–P12. It supports up to 2 UART channels, 3 I²C channels, and 2 CSI channels - though pin count limits concurrent use. All interfaces are register-controlled and supported in Renesas' e² studio and CS+ IDE for the R5F1016DASM#70.
What is the operating temperature range for the R5F1016DASM#70?
The R5F1016DASM#70 is rated for industrial operation from −40°C to +85°C, as indicated by the "D" suffix in its part number. This qualifies it for deployment in harsh environments such as factory automation controllers, outdoor metering equipment, and industrial gateways - without derating or additional thermal management beyond standard PCB layout guidelines for the R5F1016DASM#70.
