Renesas R5F10Y14DSP#50

Overview

R5F10Y14DSP#50 from Renesas Electronics is a 16-bit RL78/G10 microcontroller in 16-pin SSOP package, featuring 1 KB flash, 128 B RAM, 2.0–5.5 V operation, ultra-low power consumption (46 µA/MHz active, 0.61 µA STOP), and integrated peripherals including UART, I²C, two CSI channels, 7-channel 10-bit ADC, and four 16-bit timer channels - deployed in battery-powered sensor nodes and industrial control interfaces.

For engineers reviewing the R5F10Y14DSP#50 datasheet, R5F10Y14DSP#50 pinout, R5F10Y14DSP#50 application, or R5F10Y14DSP#50 equivalent, key selection criteria include its 16-pin SSOP footprint, 1 KB flash/128 B RAM configuration, -40°C to +85°C industrial temperature grade (D-suffix), embossed tape packaging (#50), and verified support for low-power wake-up via KR interrupts and TI0x inputs.

Technical Context

The R5F10Y14DSP#50 implements the RL78-S1 core with Harvard architecture and 3-stage pipeline, enabling 78% of instructions in 1–2 clock cycles. It uses a high-speed on-chip oscillator (1.25–20 MHz, ±2% accuracy at -20°C to +85°C) as default system clock and supports external crystal (X1/X2) or EXCLK input up to 20 MHz.

Its peripheral set includes SAU0 (UART + I²C + 2×CSI), TAU0 with four 16-bit timer channels supporting PWM output, 7-channel 10-bit ADC with 3.4 µs conversion time and internal 0.815 V reference (enabled only in 16-pin variants), and six-key interrupt (KR0–KR5) with programmable debounce - all operating under single-supply 2.0–5.5 V with full -40°C to +85°C ambient rating.

FAQ

What is the maximum operating frequency of the R5F10Y14DSP#50?

The R5F10Y14DSP#50 supports a maximum system clock frequency of 20 MHz using either the high-speed on-chip oscillator or external crystal/EXCLK input. At 20 MHz, its minimum instruction execution time is 0.05 µs (VDD ≥ 2.7 V), enabling real-time response in time-critical embedded functions. The R5F10Y14DSP#50 maintains this performance across its full -40°C to +85°C industrial temperature range.

Does the R5F10Y14DSP#50 support hardware debugging?

Yes, the R5F10Y14DSP#50 integrates a 1-wire on-chip debug function accessible via the TOOL0 pin (P40), enabling full in-circuit debugging, flash programming, and real-time variable inspection without requiring additional debug headers. This capability is fully supported in Renesas' E2 studio and CS+ IDEs, and the R5F10Y14DSP#50 debug interface operates reliably across its rated voltage and temperature range.

What analog features are included in the R5F10Y14DSP#50?

The R5F10Y14DSP#50 includes a 7-channel 10-bit successive approximation register (SAR) ADC with 3.4 µs conversion time, internal 0.815 V reference voltage (IVREF0), and support for 2.4 V analog input range. It does not include an integrated comparator - that feature is exclusive to higher-pin-count variants like R5F10Y44DSP#50. All ADC channels are accessible on Port 0 pins (P00–P07).

Can the R5F10Y14DSP#50 operate from a 2.0 V supply?

Yes, the R5F10Y14DSP#50 is fully specified for operation from 2.0 V to 5.5 V, including all peripherals and flash programming. At 2.0 V, the high-speed on-chip oscillator is limited to 1.25–5 MHz, and the maximum external clock frequency is reduced to 5 MHz. The R5F10Y14DSP#50 maintains full functionality - including ADC, UART, and timers - across this entire voltage range, with guaranteed DC/AC characteristics per datasheet Section 2.

What is the purpose of the KR pins on the R5F10Y14DSP#50?

The KR0–KR5 pins on the R5F10Y14DSP#50 implement a dedicated key return interface for matrix keypad scanning or capacitive touch sensing, with built-in hardware debounce and wake-up capability from STOP mode. These pins are mapped to Port 0 and Port 4 (P03, P04, P05, P06, P07, P40), and the R5F10Y14DSP#50 supports up to six keys without external circuitry - reducing BOM cost and PCB area in HMI designs.
