Renesas R5F1016ADSP#V0

Overview

R5F1016ADSP#V0 from Renesas is a 20-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 32 KB flash, 2 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V across -40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates an 8-bit A/D converter (6 channels), real-time clock, UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP/SNOOZE modes-ideal for battery-powered sensor nodes and industrial control panels.

For engineers reviewing the R5F1016ADSP#V0 datasheet, R5F1016ADSP#V0 pinout, R5F1016ADSP#V0 application, or R5F1016ADSP#V0 equivalent, key selection criteria include its 20-pin LSSOP package, absence of on-chip data flash, industrial-grade temperature rating, and support for background data flash programming in compatible variants (not this part).

Technical Context

The R5F1016ADSP#V0 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). Its memory map spans 1 MB address space, with general-purpose register banks enabling efficient context switching in interrupt-driven firmware.

Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, DMA controller (2 channels), and multiple low-power modes-HALT (66 μA/MHz), STOP (0.57 μA with RTC+LVD active), and SNOOZE-enabling deterministic wake-up latency for time-critical event handling in energy-constrained systems.

FAQ

What is the maximum operating frequency and performance of the R5F1016ADSP#V0?

The R5F1016ADSP#V0 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this using a 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -40°C to +85°C. The R5F1016ADSP#V0 maintains full peripheral functionality-including UART, SPI, I²C, and ADC-at maximum frequency without throttling.

Does the R5F1016ADSP#V0 include on-chip data flash memory?

No, the R5F1016ADSP#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), it provides 32 KB of code flash and 2 KB of RAM only. For applications requiring non-volatile parameter storage, consider the R5F1006ADSP#V0, which includes 4 KB of data flash alongside identical code flash and package.

What package type and pin count does the R5F1016ADSP#V0 use?

The R5F1016ADSP#V0 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65-mm pitch), identified by the "SP" suffix and "#V0" tray packaging code. This JEDEC MS-013AC-compliant package supports surface-mount assembly and provides 16 general-purpose I/O pins plus dedicated analog, serial, and power terminals as defined in the RL78/G13 pinout specification.

What low-power modes are supported by the R5F1016ADSP#V0?

The R5F1016ADSP#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA-enabling decade-long battery operation. HALT mode consumes 66 μA/MHz, and SNOOZE allows selected peripherals (e.g., UART) to remain active while CPU sleeps, reducing average system power in polling-based communication.

Can the R5F1016ADSP#V0 interface directly with 1.8 V or 2.5 V logic devices?

Yes, the R5F1016ADSP#V0 supports different-potential interface operation, allowing direct connection to 1.8 V, 2.5 V, and 3.0 V devices without external level shifters. Its I/O ports tolerate these voltages when configured appropriately, and the internal voltage regulator ensures stable core operation across the full 1.6–5.5 V supply range-making the R5F1016ADSP#V0 ideal for mixed-voltage embedded systems.
