Product details
Overview
R5F101ACASP#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 (26-channel), RTC, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101ACASP#30 datasheet, R5F101ACASP#30 pinout, R5F101ACASP#30 application, or R5F101ACASP#30 equivalent, key selection criteria include its LSSOP-30 package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A-grade), and support for background data flash programming via external library.
Technical Context
The R5F101ACASP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz sub-clock mode). It integrates a 12-bit interval timer, real-time clock with calendar/alarm, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes up to 26 analog inputs routed to an 8/10-bit SAR ADC with internal 1.45 V reference and temperature sensor, two UART channels (one LIN-capable), three I²C/Simplified I²C modules, and two to eight CSI (SPI-compatible) interfaces - all configurable under single-voltage 1.6–5.5 V operation.

FAQ
What is the flash memory configuration of the R5F101ACASP#30?
The R5F101ACASP#30 contains 16 KB of on-chip code flash memory and no integrated data flash memory - consistent with the R5F101x series designation. Its flash block size is 1 KB, and it supports self-programming with boot-swap and flash-shield window functions using Renesas' Flash Self-Programming Library.
Does the R5F101ACASP#30 support hardware debugging?
Yes, the R5F101ACASP#30 includes on-chip debug functionality compatible with Renesas E2 or E2 Lite debuggers. Pins P11 (TOOLRxD) and P12 (TOOLTxD) provide dedicated debug serial interface, enabling full break-point, step-through, and memory inspection capabilities without requiring additional debug headers.
What are the key low-power modes supported by the R5F101ACASP#30?
The R5F101ACASP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA - enabling decade-long operation on coin cells. SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate while CPU remains halted, reducing wake-up latency versus full STOP.
Can the R5F101ACASP#30 interface directly with 1.8 V logic devices?
Yes, the R5F101ACASP#30 supports different-potential interface operation. Its I/O ports can be configured for TTL input buffer and N-ch open-drain output with VDD withstand voltage, allowing safe connection to 1.8 V, 2.5 V, or 3 V external devices without level shifters - verified per datasheet Section 1.1 Features.
Is there an internal temperature sensor in the R5F101ACASP#30?
Yes, the R5F101ACASP#30 integrates a factory-calibrated temperature sensor accessible via the 10-bit ADC. It is selectable only in HS (high-speed main) mode and provides typical accuracy of ±3°C over -40°C to +85°C - useful for thermal monitoring in fan control or battery management applications.
