Product details
Overview
R5F1006CASM#70 from Renesas is a 20-pin, 16 KB flash, 2 KB RAM RL78/G13 16-bit microcontroller with integrated data flash (4 KB), real-time clock, 10-bit ADC (6 channels), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered sensor nodes and industrial control interfaces.
For engineers reviewing the R5F1006CASM#70 datasheet, R5F1006CASM#70 pinout, R5F1006CASM#70 application, or R5F1006CASM#70 equivalent, key selection criteria include its TSSOP-20 package, -40°C to +85°C industrial-grade temperature range (D-grade), 1.6–5.5 V supply, and support for HALT/STOP/SNOOZE low-power modes in space-constrained embedded designs.
Technical Context
The R5F1006CASM#70 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 ultra-low-speed mode). It integrates on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.
Its peripheral set includes two UART/LIN channels, three I²C/Simplified I²C channels, two CSI/SPI channels, eight 16-bit timer channels, one 12-bit interval timer, one calendar RTC with alarm and correction, and a watchdog timer driven by dedicated low-speed oscillator - all optimized for deterministic real-time control in resource-limited systems.

It operates independently in STOP mode using the 32.768 kHz subsystem clock, enabling precise timekeeping without external components or continuous core activity.
What are the memory resources allocated to the R5F1006CASM#70?
The R5F1006CASM#70 provides 16 KB of code flash memory (1 KB erase blocks), 4 KB of data flash memory (1M write endurance), and 2 KB of on-chip RAM. The flash library reserves RAM starting at address FF300H for self-programming operations - a fixed allocation confirmed in the RL78/G13 datasheet revision 3.80.
Can the R5F1006CASM#70 operate across the full industrial temperature range?
Yes, the R5F1006CASM#70 is rated for –40°C to +85°C operation (D-grade), meeting industrial ambient requirements. Its voltage detector (LVD) offers 14 selectable threshold levels, and the high-accuracy on-chip oscillator maintains ±1.0% stability across this full range - ensuring reliable timing and reset behavior in harsh environments.
How many analog input channels does the R5F1006CASM#70 support?
The R5F1006CASM#70 supports six analog input channels (ANI0–ANI5) with 10-bit resolution. Pins P20, P21, P22, and P147 are explicitly assigned to ANI0, ANI1, ANI2, and ANI18 respectively in the TSSOP-20 pinout - providing flexible analog sensing capability within its compact 20-pin footprint.
