Renesas R5F1016DDSP#V0

Overview

R5F1016DDSP#V0 from Renesas is a 20-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 32 KB flash memory, 2 KB RAM, and no data flash, designed for ultra-low-power industrial applications operating from −40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes just 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode, and integrates 10-bit ADC (6 channels), UART, I²C, and 16-bit timers.

For engineers reviewing the R5F1016DDSP#V0 datasheet, R5F1016DDSP#V0 pinout, R5F1016DDSP#V0 application, or R5F1016DDSP#V0 equivalent, key selection criteria include its 20-pin LSSOP package, absence of data flash, industrial-grade temperature range, low-power HALT/STOP/SNOOZE modes, and support for LIN-bus-capable UART interfaces in space-constrained embedded control designs.

Technical Context

The R5F1016DDSP#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, with on-chip resources including 32 KB code flash (1 KB block size), 2 KB RAM, and hardware peripherals such as DMA (2-channel), multiplier/divider, and real-time clock with calendar and alarm functions.

Power management includes an on-chip POR circuit, 14-level voltage detector (LVD) with interrupt/reset options, and multiple low-power modes-HALT, STOP, and SNOOZE-enabling precise trade-offs between wake-up latency and energy consumption. The device supports 1.6–5.5 V operation and features I/O ports configurable as N-ch open drain (6 V tolerant), TTL input, or with internal pull-up resistors.

FAQ

What is the maximum operating frequency and performance of the R5F1016DDSP#V0?

The R5F1016DDSP#V0 operates up to 32 MHz and delivers 41 DMIPS. Its RL78 CPU core achieves a minimum instruction execution time of 0.03125 μs in high-speed mode using the on-chip oscillator. This performance level supports real-time control loops, sensor fusion, and basic communication stack processing without external acceleration.

Does the R5F1016DDSP#V0 include data flash memory?

No, the R5F1016DDSP#V0 does not include data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), this variant provides only code flash (32 KB) and SRAM (2 KB). Applications requiring nonvolatile parameter storage must use external EEPROM or leverage code flash sectors with wear-leveling firmware.

What package type and pin count does the R5F1016DDSP#V0 use?

The R5F1016DDSP#V0 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65 mm pitch) with tray packaging denoted by the #V0 suffix. This compact, surface-mount package supports automated assembly and is optimized for space-constrained industrial control boards.

Which low-power modes are supported by the R5F1016DDSP#V0, and what is its lowest current draw?

The R5F1016DDSP#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) - enabling decade-long battery operation in metering and wireless sensor applications where periodic wake-up is required.

Can the R5F1016DDSP#V0 interface directly with LIN bus transceivers?

Yes, the R5F1016DDSP#V0's UART peripheral supports LIN-bus protocol (LIN 2.x compliant) in both master and slave configurations. Its UART module includes break detection, sync field handling, and checksum generation - allowing direct connection to standard LIN transceivers like the TJA1020 without external protocol translation.
