Overview
R5F1054AASP#10 from Renesas Electronics is a 16-pin RL78/G11 16-bit microcontroller designed for ultra-low-power general-purpose embedded control. It integrates 16 KB code flash, 2 KB data flash, and 1.5 KB RAM; operates from 1.6 V to 5.5 V; delivers 33 DMIPS at 24 MHz; and supports true low-power modes (58.3 μA/MHz active, 0.64 μA STOP). It is used in battery-powered sensor nodes, smart home controllers, and industrial monitoring modules requiring reliable mixed-signal integration.
For engineers reviewing the R5F1054AASP#10 datasheet, R5F1054AASP#10 pinout, R5F1054AASP#10 application, or R5F1054AASP#10 equivalent, key selection considerations include its 16-pin SSOP package, dual UART + quad I²C + dual CSI interfaces, 8-channel 10-bit ADC, dual 8-bit DAC outputs, and support for on-chip debug with flash self-programming - all within a -40°C to +85°C consumer-grade temperature range.
Technical Context
The R5F1054AASP#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 μs at 24 MHz high-speed on-chip oscillator). It features a multi-clock system with selectable high-speed (up to 24 MHz), middle-speed (4/2/1 MHz), and low-speed (15 kHz) on-chip oscillators, plus external crystal support (1–20 MHz).
Its peripheral set includes a 4-channel 16-bit Timer Array Unit (TAU), 12-bit interval timer, watchdog timer, Data Transfer Controller (DTC) with 22 activation sources, Event Link Controller (ELC) with 16 event inputs, and dual independent serial array units supporting UART, CSI, and simplified I²C protocols - enabling deterministic real-time peripheral coordination without CPU intervention.
