It integrates 16 KB code flash, 2 KB data flash, 1.5 KB RAM, 10-channel 10-bit ADC, dual 8-bit DACs, two comparators, PGA, and supports 24 MHz operation delivering 33 DMIPS. It operates across 1.6–5.5 V and targets battery-powered industrial sensors and smart home controllers.
For engineers reviewing the R5F1056AGSP#30 datasheet, R5F1056AGSP#30 pinout, R5F1056AGSP#30 application, or R5F1056AGSP#30 equivalent, key selection criteria include its 20-pin LSSOP package with 17 I/Os, industrial-grade −40°C to +105°C temperature range (G-grade), integrated voltage detector with 14-level LVD, and SNOOZE mode for low-latency wake-up from ultra-low-power STOP mode.
Technical Context
The R5F1056AGSP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 μs at 24 MHz). It features a multi-clock system with high-speed on-chip oscillator (±1.0% accuracy, 24 MHz max), middle-speed (4 MHz), and low-speed (15 kHz) oscillators - all selectable via software.
Peripheral integration includes Event Link Controller (ELC) supporting 17 event inputs and 4 trigger outputs, Data Transfer Controller (DTC) with 23 activation sources, and Serial Array Unit supporting four CSI channels, two UARTs, and four simplified I²C interfaces - enabling flexible peripheral chaining without CPU intervention.

FAQ
What is the maximum operating frequency and performance of the R5F1056AGSP#30?
The R5F1056AGSP#30 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 33 DMIPS of processing performance. Its minimum instruction execution time is 0.04167 μs under these conditions, and it supports configurable clock modes including HS, LS, LV, and LP for dynamic power/performance tuning.
Does the R5F1056AGSP#30 support in-system programming and secure firmware updates?
Yes, the R5F1056AGSP#30 supports self-programming of both code and data flash memory with boot swap functionality and flash shield window protection. Data flash supports background operation (BGO), allowing full CPU execution during rewrites - critical for secure over-the-air updates without system interruption.
How many analog input channels does the R5F1056AGSP#30 provide, and what reference options are available?
The R5F1056AGSP#30 includes 10 external analog input channels (ANI0–ANI3, ANI16–ANI22) plus one internal temperature sensor. It supports AVREFP/AVREFM as external differential references and an internal 1.45 V reference, enabling accurate ratiometric or absolute measurements across its 1.6–5.5 V supply range.
What low-power modes are available on the R5F1056AGSP#30, and what is the lowest achievable current draw?
The R5F1056AGSP#30 offers HALT, STOP, and SNOOZE modes. In STOP mode with only the low-voltage detector (LVD) active, it draws just 0.64 μA - verified at TA = −40°C to +105°C. SNOOZE mode enables peripheral-triggered wake-up with sub-μs latency while maintaining ultra-low quiescent current.
Is the R5F1056AGSP#30 pin-compatible with other RL78/G11 variants such as the R5F1054A or R5F1057A?
No, the R5F1056AGSP#30 is not pin-compatible with R5F1054AGSP#30 (16-pin SSOP) or R5F1057AGNA#U0 (24-pin HWQFN). Each variant has distinct pin counts, layouts, and I/O allocations - for example, the 20-pin LSSOP package of R5F1056AGSP#30 provides 17 I/Os versus 13 in the 16-pin version and 21 in the 24-pin version.
