Product details
Overview
R5F1016CASP#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), 1.6–5.5 V supply, and integrated 10-bit ADC (6 channels), RTC, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1016CASP#30 datasheet, R5F1016CASP#30 pinout, R5F1016CASP#30 application, or R5F1016CASP#30 equivalent, key selection criteria include its 30-pin LSSOP package, absence of data flash memory, -40°C to +85°C industrial temperature grade (D-grade), and support for SNOOZE mode wake-up via serial interface or external interrupt.
Technical Context
The R5F1016CASP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller with 2 channels.
Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm/correction functions, one watchdog timer, and serial interfaces: up to 2 CSI (SPI-compatible), 2 UART/LIN, and 3 I²C channels - all configurable without external components.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006CASP#30 | Includes 4 KB data flash memory; otherwise identical core/peripherals/package. | Required where field firmware updates or parameter storage (e.g., calibration tables) must persist across power cycles. | Select R5F1006CASP#30 if non-volatile parameter retention is needed; R5F1016CASP#30 reduces cost where only code flash suffices. |
| RL78/G14 R5F1116CSP#30 | Same pinout and footprint; adds 16 KB data flash, enhanced security (AES engine), and higher max frequency (48 MHz). | Suitable for secure firmware updates, encrypted sensor data, or higher-performance control loops demanding >32 MHz. | Choose R5F1116CSP#30 only when AES encryption or >32 MHz operation is mandatory; R5F1016CASP#30 offers optimal cost/power for basic control. |
Compared with R5F1006CASP#30 and R5F1116CSP#30, the R5F1016CASP#30 provides the lowest bill-of-materials cost and smallest power footprint for applications that do not require persistent data storage or cryptographic acceleration - making it ideal for high-volume, battery-constrained edge nodes.

FAQ
What is the maximum operating frequency of the R5F1016CASP#30?
The R5F1016CASP#30 supports a maximum CPU clock frequency of 32 MHz using the on-chip high-speed oscillator. This frequency is achievable across the full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature, with oscillator accuracy maintained at ±1.0% under those conditions. The R5F1016CASP#30 does not require an external crystal to reach this speed.
Does the R5F1016CASP#30 include data flash memory?
No, the R5F1016CASP#30 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash is omitted - unlike "100" variants (e.g., R5F1006CASP#30) which integrate 4 KB of data flash. This omission reduces cost and simplifies firmware update architecture where non-volatile parameter storage is unnecessary.
Which package type and pin count does the R5F1016CASP#30 use?
The R5F1016CASP#30 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65 mm lead pitch), designated by the "SP" suffix and "A" pin-count code in the part number. It is RoHS-compliant, JEDEC MO-153 registered, and compatible with standard surface-mount reflow processes including lead-free soldering profiles.
What low-power modes are supported by the R5F1016CASP#30?
The R5F1016CASP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with RTC and LVD active, it draws just 0.57 μA - enabling multi-year battery life. SNOOZE mode permits selective peripheral wake-up (e.g., UART receive) while keeping CPU halted, reducing average current versus full wake-up cycles in intermittent communication scenarios.
Can the R5F1016CASP#30 operate from a 1.8 V supply?
Yes, the R5F1016CASP#30 operates across a 1.6 V to 5.5 V supply range, fully specified down to 1.6 V. At 1.8 V, it supports all core functions including 32 MHz operation (with reduced oscillator accuracy tolerance), ADC conversion (using internal 1.45 V reference), and RTC/calendar functionality - making it suitable for single-cell LiFePO₄ or regulated 1.8 V rail applications.
