Product details
Overview
R5F1016CASP#50 from Renesas is a 20-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller optimized for ultra-low-power general-purpose embedded control. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, achieves 66 μA/MHz active current and 0.57 μA RTC+LVD standby, and targets battery-powered sensor nodes and industrial I/O modules.
For engineers reviewing the R5F1016CASP#50 datasheet, R5F1016CASP#50 pinout, R5F1016CASP#50 application, or R5F1016CASP#50 equivalent, key selection criteria include its 20-pin LSSOP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (A), and support for HALT/STOP/SNOOZE low-power modes with integrated RTC and LVD.
Technical Context
The R5F1016CASP#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its 1 MB address space and four banks of (8-bit × 8) general-purpose registers enable efficient real-time task handling in resource-constrained systems.
It integrates a 16-bit timer (8 channels), 12-bit interval timer, real-time clock with calendar/alarm functions, 8/10-bit A/D converter (6 analog inputs), and serial interfaces including CSI (SPI-compatible), UART/LIN, and I²C - all operating within the same 1.6–5.5 V supply range and qualified for industrial ambient temperatures.

The R5F1016CASP#50 operates up to 32 MHz and delivers 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core efficiency at full speed, enabling deterministic real-time response in control loops, sensor fusion, and communication protocol stacks without requiring external accelerators or higher-power alternatives.
Does the R5F1016CASP#50 include on-chip data flash memory?
No, the R5F1016CASP#50 does not include data flash memory. As indicated by the '1' in the second digit of its part number (R5F1016C...), it belongs to the data-flash-free variant of the RL78/G13 family. This simplifies firmware updates and reduces cost for applications where non-volatile parameter storage is handled externally or is unnecessary.
What package type and pin count does the R5F1016CASP#50 use?
The R5F1016CASP#50 uses a 20-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), designated by the 'SP' suffix and #50 embossed tape packaging specification. This compact, surface-mount package supports automated assembly and provides mechanical robustness for industrial environments.
What low-power modes are supported by the R5F1016CASP#50, and what is its lowest current consumption?
The R5F1016CASP#50 supports HALT, STOP, and SNOOZE modes. Its lowest operational current is 0.57 μA in STOP mode with only the real-time clock and low-voltage detector active - verified across the -40°C to +85°C industrial temperature range and 1.6–5.5 V supply.
Is an external crystal required for accurate timing on the R5F1016CASP#50?
No, the R5F1016CASP#50 includes a high-accuracy on-chip oscillator rated at +/-1.0% over -20°C to +85°C and 1.8–5.5 V, supporting frequencies from 1 MHz to 32 MHz. An external crystal is optional and only needed for applications requiring tighter timing tolerance than +/-1.0%.
