Product details
Overview
R5F1054AGSP#30 from Renesas Electronics is a 16-pin, industrial-grade RL78/G11 16-bit microcontroller featuring 16 KB flash, 2 KB data flash, and 1.5 KB RAM. It operates from 1.6 V to 5.5 V, delivers 33 DMIPS at 24 MHz, and achieves ultra-low power consumption (58.3 μA/MHz active, 0.64 μA in LVD-only mode), making it ideal for battery-powered sensor nodes and smart home control modules.
For engineers reviewing the R5F1054AGSP#30 datasheet, R5F1054AGSP#30 pinout, R5F1054AGSP#30 application, or R5F1054AGSP#30 equivalent, key selection considerations include its 16-pin SSOP package, dual UART + quad I²C interfaces, 8-channel 10-bit ADC with internal reference, integrated DTC and ELC for low-CPU-load peripheral coordination, and industrial temperature range (−40°C to +105°C).
Technical Context
The R5F1054AGSP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.04167 μs (24 MHz high-speed on-chip oscillator) to 66.6 μs (15 kHz low-speed oscillator). It integrates a 12-bit interval timer, four 16-bit TAU timer channels, two comparators, one PGA, and a hardware multiplier/divider unit.
Its clock system includes selectable high-speed (up to 24 MHz ±1.0%), middle-speed (4/2/1 MHz), and low-speed (15 kHz) on-chip oscillators, plus external crystal support (1–20 MHz depending on VDD). The event link controller (ELC) enables direct peripheral-to-peripheral triggering across 16 event sources and 4 trigger outputs without CPU intervention.

FAQ
What is the maximum operating frequency and associated power consumption of the R5F1054AGSP#30?
The R5F1054AGSP#30 achieves 33 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency, active current consumption is 58.3 μA per MHz. In STOP mode with only the low-voltage detector (LVD) active, it draws just 0.64 μA - a critical specification for battery-powered applications where duty-cycled wake-up is required. The device supports multiple clock sources including external crystals up to 20 MHz depending on VDD level.
Does the R5F1054AGSP#30 support in-system programming and secure firmware updates?
Yes, the R5F1054AGSP#30 includes an on-chip debug function and full self-programming capability for both code and data flash memory. It supports boot swap functionality for safe firmware updates and flash shield window protection to prevent unauthorized readout. The flash library uses RAM starting at address FF900H, and data flash supports background operation (BGO) - allowing program execution while rewriting non-volatile parameters.
How many analog input channels and what ADC resolution does the R5F1054AGSP#30 provide?
The R5F1054AGSP#30 integrates an 8-channel, 10-bit successive-approximation ADC with selectable resolution (8/10-bit). It features internal reference voltages (1.45 V) and a built-in temperature sensor. Analog inputs include ANI0–ANI3 and ANI18–ANI22, with dedicated AVREFP/AVREFM pins enabling ratiometric measurements. The ADC supports scan mode, single-conversion, and hardware-triggered conversions via ELC or timers.
What serial communication interfaces are integrated into the R5F1054AGSP#30?
The R5F1054AGSP#30 provides two UART channels, four simplified I²C interfaces (two of which support multimaster operation), and two CSI (SPI-compatible) channels. This combination enables simultaneous communication with displays, sensors, RF modules, and legacy peripherals. All interfaces support programmable baud rates, parity, and framing - and can be routed to multiple pin combinations via peripheral I/O redirection registers (PIOR0–PIOR3).
What is the industrial temperature rating and supply voltage range for the R5F1054AGSP#30?
The R5F1054AGSP#30 is qualified for industrial operation from −40°C to +105°C ambient temperature and supports a wide supply voltage range of 1.6 V to 5.5 V. Its on-chip voltage detector (LVD) offers 14 programmable threshold levels for reliable brown-out detection across this voltage span. The device also includes a power-on-reset (POR) circuit with 1.51 V ±0.06 V trip point at +105°C, ensuring robust startup under varying conditions.
