Overview
R5F1006CASM#30 from Renesas is a 32-bit RL78/G13 microcontroller in a 20-pin TSSOP package, featuring 16 KB flash memory, 2 KB RAM, and 4 KB data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and portable control units requiring integrated analog peripherals and robust low-power operation.
For engineers reviewing the R5F1006CASM#30 datasheet, R5F1006CASM#30 pinout, R5F1006CASM#30 application, or R5F1006CASM#30 equivalent, key selection criteria include its 20-pin TSSOP footprint, 16 KB code flash with self-programming, 10-bit 6-channel ADC, real-time clock with calendar, and support for LIN-bus UART - all within a -40°C to +85°C industrial temperature grade.
Technical Context
The R5F1006CASM#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs min @32 MHz to 30.5 μs @32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (2 channels), and multiplier/divider unit supporting 16×16→32-bit and 32÷32 operations.
Its peripheral set includes up to 16 I/O pins (N-ch open-drain capable), 8×16-bit timers, 1×12-bit interval timer, 1×real-time clock with alarm/calendar, 1×watchdog timer, and serial interfaces: 2×UART (LIN-capable), 2×CSI (SPI-like), and 3×I²C/Simplified I²C channels - all mapped to its 20-pin TSSOP I/O constraints.

FAQ
What is the operating temperature range for the R5F1006CASM#30?
The R5F1006CASM#30 is rated for industrial operation from –40°C to +85°C. This specification is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Section 1.1), where the "A" suffix in the part number denotes the consumer/industrial temperature grade. It does not support the extended –40°C to +105°C "G" grade.
Does the R5F1006CASM#30 include an integrated hardware LIN transceiver?
No, the R5F1006CASM#30 includes a LIN-capable UART peripheral (supporting LIN 2.2 protocol framing and baud rate generation), but it does not integrate a physical-layer LIN transceiver. An external LIN transceiver IC (e.g., TLE7259-3GE) must be used for bus-level compliance and ESD protection.
How many analog input channels are accessible on the R5F1006CASM#30?
The R5F1006CASM#30 provides four accessible analog input channels: ANI0 (P20), ANI1 (P21), ANI2 (P22), and ANI18 (P147). All are 10-bit capable and share the internal 1.45 V reference or accept external references via AVREFP/AVREFM pins.
Can the R5F1006CASM#30 execute code while rewriting its data flash memory?
Yes, the R5F1006CASM#30 supports Background Operation (BGO) for data flash. When enabled, the CPU can execute instructions from code flash while the data flash is being rewritten - essential for logging or parameter updates without interrupting real-time control loops.
What debug interface does the R5F1006CASM#30 support?
The R5F1006CASM#30 supports Renesas' on-chip debugging via the TOOLRxD/TOOLTxD/TOOLCLK pins (P11, P12, P13), compatible with E2 emulator Lite and E2 studio IDE. It does not support SWD or JTAG; debugging uses Renesas' proprietary single-wire interface over these dedicated pins.
