Product details
Overview
R5F10Y16DSP#50 from Renesas Electronics is a 16-bit RL78/G10 microcontroller in 10-pin LSSOP package, featuring 2 KB flash memory, 256 B RAM, ultra-low-power operation (46 µA/MHz active, 0.56 µA stop), and integrated peripherals including UART, I²C, CSI, 10-bit ADC (4 channels), and 2-channel 16-bit timer array - designed for battery-powered sensor nodes and compact industrial control modules.
For engineers reviewing the R5F10Y16DSP#50 datasheet, R5F10Y16DSP#50 pinout, R5F10Y16DSP#50 application, or R5F10Y16DSP#50 equivalent, key selection considerations include its 10-pin LSSOP footprint, 2.0–5.5 V supply range, -40°C to +85°C industrial temperature grade, 2 KB flash/256 B RAM configuration, and support for high-current I/O (20 mA per pin) with internal pull-up and open-drain capability.
Technical Context
The R5F10Y16DSP#50 implements the RL78-S1 core - a CISC Harvard architecture with 3-stage pipeline, where 78% of instructions execute in 1–2 clock cycles. It integrates a high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy at -20°C to +85°C) and low-speed 15 kHz oscillator for ultra-low-power wake-up.
Peripherals are tightly coupled to the core via dedicated bus interfaces: UART0 supports 7-/8-bit framing and up to 3.3 Mbps theoretical rate; SAU0 provides simplified SPI (CSI) and I²C master functions; TAU0 delivers two independent 16-bit timer channels with PWM output capability and input capture; and the 10-bit ADC achieves 3.4 µs conversion time with internal reference support.
Key Specifications
