16-bit RL78 core at 32 MHz — 64 KB flash, 20-pin package
The R5F1016EASP#30 is a 16-bit RL78/G13 microcontroller from Renesas, clocked at 32 MHz with 64 KB of on-chip flash program memory and 2 KB of RAM. The 20-LSSOP package (6.10 mm body width) limits the I/O count to 13 pins, so this part targets control applications where sensor inputs and a few actuator outputs fit within that budget — not a high-pin-count human-machine interface.
Industrial temperature grade and peripheral set
The on-chip peripherals include DMA, LVD (low-voltage detect), POR (power-on reset), PWM, and WDT — enough to build a standalone controller without external supervisor ICs. Serial connectivity covers CSI (clocked serial interface), I²C, and UART/USART. The 6-channel ADC resolves 8 or 10 bits, adequate for reading potentiometers, thermistors, or current-sense resistors at moderate sampling rates.
Active lifecycle — no end-of-life concern
Renesas lists the R5F1016EASP#30 as Active with RoHS3 compliance.
The 20-LSSOP package has a 0.65 mm typical lead pitch and a 6.10 mm body width. The tray packaging means the MCU ships in antistatic trays, not tape-and-reel — factor this into pick-and-place feeder setup if the line expects reeled parts.
I/O count trade-off vs the RL78/G14 sibling
The closest functional peer in the RL78 family is the R5F101GGAFB#30, which runs the same 32 MHz RL78 core and 64 KB flash but in a 48-pin LQFP with 34 I/O and 10 ADC channels. The R5F1016EASP#30 saves board space and cost with its 20-pin LSSOP, but the 13 I/O limit means it cannot directly drive a parallel LCD or a keypad matrix — the 34-I/O sibling handles those without port expansion.
