FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100ACASP#X0?
The R5F100ACASP#X0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's efficiency in executing real-world embedded control code, including interrupt handling, peripheral register access, and arithmetic operations - making it suitable for time-critical tasks like motor commutation and sensor sampling at sub-millisecond intervals.
Does the R5F100ACASP#X0 include an integrated temperature sensor, and what is its accuracy?
Yes, the R5F100ACASP#X0 includes a factory-calibrated on-chip temperature sensor usable in HS (high-speed main) mode. Its typical accuracy is ±2°C over the full -40°C to +85°C operating range, enabling reliable ambient temperature monitoring and thermal compensation without external components - a key advantage for sealed industrial enclosures and consumer appliances.
How much data flash memory does the R5F100ACASP#X0 provide, and what is its endurance specification?
The R5F100ACASP#X0 provides 4 KB of dedicated data flash memory, rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. This allows robust nonvolatile storage of calibration data, device configuration, or usage logs - and supports background operation so application code continues running during flash updates.
What package type and pin count does the R5F100ACASP#X0 use, and is it RoHS-compliant?
The R5F100ACASP#X0 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch) with RoHS-compliant matte tin plating. Its JEDEC MS-013AC footprint ensures compatibility with standard SMT assembly lines and reflow profiles, and the narrow-body design saves PCB area in space-constrained modules like smart meters and sensor transmitters.
Which serial communication protocols are supported by the R5F100ACASP#X0, and how many instances are available?
The R5F100ACASP#X0 supports UART/LIN (up to 4 channels), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). These interfaces share pins dynamically - for example, P10 serves as SCK00 or SCL00, and P11 as SI00, RxD0, TOOLRxD, or SDA00 - maximizing protocol flexibility without increasing pin count.
