Product details

Overview

R5F1016CASM#30 from Renesas is a 30-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated 10-bit ADC (6 channels), RTC, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.

For engineers reviewing the R5F1016CASM#30 datasheet, R5F1016CASM#30 pinout, R5F1016CASM#30 application, or R5F1016CASM#30 equivalent, key selection criteria include its LSSOP-30 package, absence of data flash memory, -40°C to +85°C industrial-grade temperature rating, and support for SNOOZE mode wake-up via serial interface or timer events.

Technical Context

The R5F1016CASM#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller supporting 2-channel transfers between SFR and RAM in just 2 clocks per 8/16-bit word.

Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm/correction functions, one watchdog timer (dedicated low-speed oscillator), and serial interfaces: up to 2 CSI (SPI-compatible), 2 UART/LIN, and 3 I²C channels - all configurable without external components.

FAQ

What is the maximum operating frequency of the R5F1016CASM#30?

The R5F1016CASM#30 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.

Does the R5F1016CASM#30 include data flash memory?

No, the R5F1016CASM#30 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash is omitted. This simplifies firmware design by removing background rewrite requirements and flash library dependencies, making it ideal for fixed-parameter applications.

What package type and pin count does the R5F1016CASM#30 use?

The R5F1016CASM#30 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), designated by the "ASM" suffix and confirmed in Table 1-1 of the RL78/G13 datasheet. It is compatible with standard surface-mount reflow profiles and supports manual soldering for prototyping.

Which serial interfaces are available on the R5F1016CASM#30?

The R5F1016CASM#30 provides two CSI (SPI-compatible) channels, two UART/LIN channels, and three I²C/Simplified I²C channels. These interfaces are multiplexed across dedicated pins and support simultaneous operation - for example, UART for host communication and I²C for sensor reading - without resource conflict.

Is the R5F1016CASM#30 qualified for industrial temperature range?

Yes, the R5F1016CASM#30 is rated for -40°C to +85°C operation (Industrial grade "D" variant), as indicated by the "D" in the ordering code structure and confirmed in the RL78/G13 datasheet Section 1.1. It meets industrial qualification standards including AEC-Q100 stress testing for reliability in harsh environments.
