Renesas R5F1016CASP#V0

Overview

R5F1016CASP#V0 from Renesas is a 20-pin RL78/G13 16-bit microcontroller with 16 KB flash memory, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V across –40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, and 16-bit timers - deployed in battery-powered sensor nodes and industrial control interfaces.

For engineers reviewing the R5F1016CASP#V0 datasheet, R5F1016CASP#V0 pinout, R5F1016CASP#V0 application, or R5F1016CASP#V0 equivalent, key selection criteria include its LSSOP-20 package, absence of on-chip data flash (R5F101x series), 20-pin I/O count, and support for low-voltage operation down to 1.6 V in consumer-grade temperature range.

Technical Context

The R5F1016CASP#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 dedicated SFRs enabling direct peripheral access without memory-mapped overhead.

Power management includes on-chip POR and 14-level LVD with selectable interrupt/reset behavior, while the DMA controller supports 2-channel transfers between SFRs and RAM in just 2 clocks per 8/16-bit operation - critical for deterministic real-time sensor data acquisition and low-latency communication stack handling.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F1016CASP#V0?

The R5F1016CASP#V0 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 supply and –20 to +85°C ambient - making the R5F1016CASP#V0 suitable for real-time control tasks without external clock components.

Does the R5F1016CASP#V0 include on-chip data flash memory?

No, the R5F1016CASP#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number (per Renesas RL78/G13 documentation), this variant omits data flash to reduce cost and die area. For applications requiring nonvolatile parameter storage, the pin-compatible R5F1006CASP#V0 (with 4 KB data flash) is the direct alternative.

What package type and pin count does the R5F1016CASP#V0 use?

The R5F1016CASP#V0 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65 mm pitch), identified by the "#V0" suffix denoting tray packaging. This package supports fine-pitch surface-mount assembly and is compatible with standard reflow profiles, making it ideal for compact, high-volume consumer electronics.

What low-power modes are supported by the R5F1016CASP#V0, and what is the lowest current consumption?

The R5F1016CASP#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA - enabling multi-year operation on coin-cell batteries. HALT mode draws 66 μA/MHz, balancing responsiveness and power savings for periodic wake-up tasks.

Which analog and serial peripherals are integrated into the R5F1016CASP#V0?

The R5F1016CASP#V0 integrates a 10-bit ADC with 6 analog input channels (including ANI0–ANI2 and ANI18), one UART channel, one I²C interface, and one CSI (SPI-compatible) channel. These peripherals enable direct interfacing with sensors, displays, and communication modules without external level shifters or protocol translators.
