Product details
Overview
R5F12008ANS#70 from Renesas Electronics is an 8-pin RL78/G15 16-bit microcontroller with 8 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V. It integrates an 8/10-bit A/D converter (3 channels), 8-channel 16-bit timer array, UART, simplified SPI (CSI), simplified I²C, and comparator-targeted for compact industrial sensor nodes and low-power control modules.
For engineers reviewing the R5F12008ANS#70 datasheet, R5F12008ANS#70 pinout, R5F12008ANS#70 application, or R5F12008ANS#70 equivalent, key selection considerations include its LSSOP-8 package, −40°C to +85°C industrial temperature grade (A), high-speed on-chip oscillator accuracy (±2.0% over full temp range), and tool interface support via TOOL0/TOOLRxD/TOOLTxD pins.
Technical Context
The R5F12008ANS#70 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting minimum instruction execution time of 0.0625 μs at 16 MHz using the high-speed on-chip oscillator. Its memory subsystem includes 8 KB code flash (1 KB block size), 1 KB data flash (512 B block, 1M rewrite cycles), and 1 KB SRAM-all accessible under single-supply operation.
Peripherals are tightly integrated: the 8/10-bit A/D converter supports up to 3 analog inputs with internal 0.815 V reference; the 8-channel TAU0 timer provides PWM outputs (2 channels configurable); and serial interfaces include one UART channel, one simplified SPI (CSI00), and one simplified I²C (IIC00), all multiplexed on port pins with programmable I/O redirection.

FAQ
What is the maximum operating frequency and oscillator accuracy of the R5F12008ANS#70?
The R5F12008ANS#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz with ±2.0% accuracy over its full operating temperature range (−40°C to +85°C). It also includes a 15 kHz low-speed on-chip oscillator for watchdog and STOP-mode timing. External crystal oscillation (X1/X2) up to 12 MHz is supported but requires external resonator components.
Does the R5F12008ANS#70 support in-circuit debugging, and which pins are used?
Yes, the R5F12008ANS#70 supports full on-chip debug functionality using three dedicated pins: P40 (TOOL0), P01 (TOOLRxD), and P03 (TOOLTxD). These enable bidirectional communication with Renesas E2 studio and CS+ IDE without external debug adapters-reducing BOM cost and board space.
How many analog input channels does the R5F12008ANS#70 have, and what reference voltage options are available?
The R5F12008ANS#70 features three analog input channels (ANI0, ANI2, ANI3) with 8/10-bit resolution. It supports internal reference voltage (0.815 V typical) and external reference via IVREF0 pin. No separate VREF pin is provided-the internal reference is fixed and calibrated at factory.
Can the R5F12008ANS#70 perform simultaneous read/write operations on code and data flash memory?
No, the R5F12008ANS#70 does not support background operation (BGO). While rewriting data flash memory, instruction execution from code flash is disabled. This requires careful firmware sequencing-typically using STOP mode during data flash writes to minimize system interruption.
What is the package type and pin count of the R5F12008ANS#70, and is it RoHS compliant?
The R5F12008ANS#70 is supplied in an 8-pin LSSOP package (4.4 × 3.6 mm, 0.65-mm pitch) with lead-free, RoHS-compliant finish. The #70 suffix indicates tray packaging per Renesas ordering conventions. Pin 1 is marked by a dot or notch, and the exposed pad variant is not used in this package type.
