Product details
Overview
R5F101AAASP#70 from Renesas is a 30-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, operating at 1.6–5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), UART, I²C, SPI, 16-bit timers, and real-time clock - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F101AAASP#70 datasheet, R5F101AAASP#70 pinout, R5F101AAASP#70 application, or R5F101AAASP#70 equivalent, key selection criteria include its 30-pin LSSOP-30 package, absence of data flash, -40°C to +85°C industrial-grade temperature range (A-grade), and compatibility with RL78 development tools including E2 studio and CS+.
Technical Context
The R5F101AAASP#70 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It uses a single-supply 1.6–5.5 V rail and includes on-chip power-on-reset, voltage detector (14-level LVD), and HALT/STOP/SNOOZE low-power states.
Peripheral integration includes one 12-bit interval timer, one real-time clock with calendar/alarm, one watchdog timer, two UART channels (LIN-capable), up to three I²C interfaces, two CSI (SPI-compatible) channels, eight 16-bit timer channels, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100AAASP#70 | Same package and pinout, but includes 4 KB data flash memory | Required for applications needing nonvolatile parameter storage (e.g., calibration tables, device IDs) | Select when field-updatable configuration data is mandatory; adds ~$0.15 cost and 1 KB flash library RAM overhead |
| RL78/G14 R5F104BAASP#70 | RL78/G14 family, 30-pin LSSOP, 64 KB flash, 5 KB RAM, includes data flash and enhanced peripherals (USB, more timers) | Targeted at next-generation designs requiring USB connectivity or larger firmware footprint | Choose for future-proofing or when migrating from G13 to G14 for added features; not pin-compatible due to different register mapping |
Compared with R5F101AAASP#70, R5F100AAASP#70 adds data flash at minimal cost and footprint impact, while RL78/G14 R5F104BAASP#70 trades pin compatibility for significantly expanded memory and USB capability - making the former ideal for incremental upgrades and the latter for new designs demanding richer peripheral sets.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101AAASP#70?
The R5F101AAASP#70 operates at up to 32 MHz and achieves 41 DMIPS performance per the RL78/G13 datasheet Rev. 3.80. This metric reflects integer execution throughput under standard benchmark conditions and is directly usable for real-time task scheduling in control applications. The R5F101AAASP#70 maintains this performance across its full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature.
Does the R5F101AAASP#70 include data flash memory, and how does that affect firmware design?
No, the R5F101AAASP#70 does not include data flash memory - only 16 KB of code flash and 2 KB of RAM. This means parameters requiring nonvolatile storage (e.g., calibration offsets, device configuration) must be retained externally or managed via wear-leveling in code flash. The R5F101AAASP#70's flash library reserves RAM at address FF300H for self-programming operations, and firmware must allocate alternate storage strategies compared to data-flash-equipped variants like R5F100AAASP#70.
What package type and pin count does the R5F101AAASP#70 use, and is it compatible with standard LSSOP footprints?
The R5F101AAASP#70 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm pitch), specified as PLSP0030JB-B in Renesas documentation. It is fully compatible with JEDEC MS-013AC standard LSSOP-30 footprints and matches land patterns used for other 30-pin LSSOP MCUs - enabling drop-in replacement in existing layouts where pin functions align and voltage/temperature requirements match.
Which serial communication interfaces are integrated into the R5F101AAASP#70, and how many instances of each are available?
The R5F101AAASP#70 integrates two UART channels (both LIN-capable), up to three I²C interfaces, and two CSI channels (SPI-compatible). All are multiplexed onto dedicated pins with flexible function selection via register configuration. No hardware USB or CAN is present - those require external transceivers or migration to RL78/G14/G1A families. The R5F101AAASP#70's serial interface count supports concurrent sensor bus (I²C), debug (UART), and actuator control (CSI) without external bridging.
What low-power modes does the R5F101AAASP#70 support, and what is the lowest achievable current consumption?
The R5F101AAASP#70 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it draws 0.57 μA at VDD = 3.0 V and TA = 25°C - the lowest guaranteed current per datasheet Rev. 3.80. This mode retains RAM content and allows wake-up via RTC alarm or external interrupt, making it optimal for periodic-sampling applications. The R5F101AAASP#70 achieves 66 μA/MHz in active mode, confirming its true low-power platform classification.
