Product details
Overview
R5F100CGALA#U0 from Renesas is a 36-pin, 5 V-tolerant RL78/G13 16-bit microcontroller with 32 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40°C to +105°C (industrial G-grade). It integrates 12-bit RTC, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power STOP mode (0.57 μA) for battery-powered industrial sensing and control.
For engineers reviewing the R5F100CGALA#U0 datasheet, R5F100CGALA#U0 pinout, R5F100CGALA#U0 application, or R5F100CGALA#U0 equivalent, key selection criteria include its WFLGA-36 package (4 × 4 mm, 0.5 mm pitch), integrated data flash with 1M rewrite cycles, real-time clock with calendar/alarm, and support for SNOOZE-mode peripheral wake-up without CPU intervention.
Technical Context
The R5F100CGALA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features on-chip debug, self-programming with boot swap, and background operation during data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes; voltage detector (LVD) with 14 selectable levels; and POR circuit. Peripheral integration covers up to 16× 16-bit timers, 3× I²C channels, 4× UART/LIN channels, and DMA controller with 4 channels for efficient memory-to-peripheral transfers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time response in resource-constrained embedded systems. |
| Max Clock | 32 MHz via high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V, TA = –20 to +85°C); eliminates external crystal for cost-sensitive designs. |
| Flash / Data Flash / RAM | 32 KB code flash (1 KB block size), 4 KB data flash (1M rewrite cycles, BGO supported), 2 KB SRAM; supports firmware updates and parameter storage without external EEPROM. |
| Low-Power Modes | STOP mode draws 0.57 μA (RTC + LVD active); HALT draws 66 μA/MHz; enables multi-year battery life in metering and sensor nodes. |
| Analog Peripherals | 10-bit ADC with 26 input channels, internal 1.45 V reference, and temperature sensor; suitable for direct analog signal acquisition in HVAC and industrial monitoring. |
| Package & Temp Range | WFLGA-36 (4 × 4 mm, 0.5 mm pitch), industrial G-grade (–40°C to +105°C); compact footprint for space-limited PCBs in harsh thermal environments. |
| Serial Interfaces | Up to 3 I²C, 4 UART/LIN, and 8 CSI (SPI-compatible) channels; enables concurrent communication with displays, sensors, and CAN transceivers via LIN gateway functions. |
Pinout & Package
Package: WFLGA-36 (4 × 4 mm, 0.5 mm pitch, 36-terminal wafer-level chip-scale package with solder bumps).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains support mixed-voltage I/O (1.8/2.5/3.0 V interface capability) and noise-isolated analog section. |
| P00–P07 | General-purpose I/O with N-ch open drain | Configurable as TTL input, pull-up enabled, or 6 V-tolerant output; allows direct connection to legacy 5 V logic or low-voltage peripherals. |
| P10–P17 | Multi-function pins (SCK00/SCL00, SI00/RxD0, etc.) | Shared UART0/SPI0/I²C0 signals enable flexible peripheral mapping; TOOLRxD supports on-chip debug without dedicated JTAG header. |
| P20–P27 | Analog inputs (ANI0–ANI7), AVREFP/AVREFM | Dedicated analog voltage reference pins ensure stable ADC conversion across supply and temperature variations. |
| RESET | Active-low reset input | Accepts external reset or internal POR/LVD assertion; debounced internally to prevent spurious resets in noisy environments. |
| CLKP/CLKM | Optional external crystal oscillator inputs | Supports 32.768 kHz crystal for RTC accuracy; not required when using internal oscillator for main clock. |
Key Features
| Feature | Design Value |
|---|---|
| Self-programming with boot swap | Enables field firmware updates with zero downtime: active bank remains operational while new code writes to standby bank. |
| Background operation (BGO) | Allows CPU to execute application code from flash while data flash is rewritten-critical for logging and configuration retention. |
| SNOOZE mode | Permits UART, I²C, or timer interrupts to wake peripherals and trigger ADC conversions without waking CPU, reducing average system power. |
| On-chip voltage detector (LVD) | 14 programmable threshold levels (1.6–4.2 V) enable precise brown-out detection and graceful shutdown before data corruption occurs. |
| Real-time clock (RTC) | Full calendar (year/month/day/hour/min/sec), alarm, and auto-correction; operates independently in STOP mode using 32.768 kHz clock. |
| DMA controller (4-channel) | Transfers data between peripherals and RAM in 2 clocks per 8/16-bit word-offloads CPU during high-bandwidth sensor or display refresh tasks. |

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F100CGALA#U0?
The R5F100CGALA#U0 features a high-accuracy on-chip oscillator configurable up to 32 MHz with ±1.0% tolerance across VDD = 1.8–5.5 V and TA = –20°C to +85°C. This eliminates the need for an external crystal in most applications, reducing BOM cost and PCB area while maintaining timing integrity for UART, SPI, and real-time control loops.
Does R5F100CGALA#U0 support in-system programming and secure firmware updates?
Yes, R5F100CGALA#U0 supports full in-system programming via on-chip debug interface and includes flash shield window and block erase prohibition features. Its self-programming capability with boot swap function enables safe dual-bank firmware updates-ensuring R5F100CGALA#U0 maintains operation during field upgrades without risk of bricking.
How many analog input channels and what ADC resolution does R5F100CGALA#U0 provide?
R5F100CGALA#U0 integrates a 10-bit successive approximation ADC with up to 26 analog input channels (ANI0–ANI25), internal 1.45 V reference voltage, and on-chip temperature sensor. This enables simultaneous acquisition of multiple sensor signals-such as voltage, current, temperature, and humidity-in a single R5F100CGALA#U0-based measurement system.
What low-power modes are available on R5F100CGALA#U0, and what is the lowest current draw?
R5F100CGALA#U0 offers HALT, STOP, and SNOOZE modes. In STOP mode-with only RTC and LVD active-it draws just 0.57 μA at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current makes R5F100CGALA#U0 ideal for battery-powered applications requiring multi-year operation without maintenance.
Is R5F100CGALA#U0 pin-compatible with other RL78/G13 variants in the same package?
R5F100CGALA#U0 uses the WFLGA-36 package and shares identical pinout with all other RL78/G13 devices in the same 36-pin variant (e.g., R5F100AGALA#U0, R5F100DGALA#U0). Pin compatibility enables scalable design reuse-engineers can migrate between 16–128 KB flash options without PCB redesign, provided peripheral assignments align with target variant capabilities.
