Product details
Overview
R5F1016CASM#30 from Renesas is a 30-pin, 16 KB flash, data-flash-free RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 1.6–5.5 V supply, and integrated 10-bit ADC (6 channels), RTC, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1016CASM#30 datasheet, R5F1016CASM#30 pinout, R5F1016CASM#30 application, or R5F1016CASM#30 equivalent, key selection criteria include its LSSOP-30 package, absence of data flash memory, -40°C to +85°C industrial-grade temperature rating, and support for SNOOZE mode wake-up via serial interface or timer events.
Technical Context
The R5F1016CASM#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller supporting 2-channel transfers between SFR and RAM in just 2 clocks per 8/16-bit word.
Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm/correction functions, one watchdog timer (dedicated low-speed oscillator), and serial interfaces: up to 2 CSI (SPI-compatible), 2 UART/LIN, and 3 I²C channels - all configurable without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and low-energy interrupt response. |
| Flash Memory | 16 KB code flash (1 KB block size); supports self-programming with boot swap and flash shield window. |
| RAM | 2 KB on-chip RAM; sufficient for real-time control stacks and small buffer handling in sensor firmware. |
| Supply Voltage | 1.6 V to 5.5 V; allows direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V peripherals without level shifters. |
| Power Modes | HALT, STOP, and SNOOZE modes; SNOOZE enables UART/SPI wake-up while retaining RAM and register context. |
| ADC | 10-bit resolution, 6 input channels, internal 1.45 V reference; suitable for precision analog sensing in HVAC and metering. |
| Operating Temperature | -40°C to +85°C (Industrial grade D); qualified for deployment in factory automation and outdoor edge devices. |
Pinout & Package
Package: 30-pin plastic LSSOP (7.62 mm, 0.65-mm pitch), JEDEC MS-013AC compliant, 1.27 mm height - optimized for compact PCB layouts with hand-solderable leads and thermal reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD/VSS pairs ensure stable core and I/O rail decoupling; supports mixed-voltage I/O operation. |
| P00–P07 | General-purpose I/O port | Configurable as N-ch open drain (6 V tolerant), TTL input, or pull-up; enables direct connection to 1.8/2.5/3 V logic. |
| P10/P11 | SCK00/SI00/RxD0 | Primary SPI clock/input and UART receive; shared pins reduce footprint while maintaining full serial debug capability. |
| P20–P22 | ANI0–ANI2 | Analog inputs with AVREFP/AVREFM references; allow ratiometric measurement using internal 1.45 V reference. |
| RESET | Active-low reset input | Accepts external reset signal or internal POR/LVD assertion; debounced internally for robust startup. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power HALT/STOP/SNOOZE modes | Reduces system standby current to sub-μA levels while preserving RAM and enabling fast wake-up from serial or timer events. |
| On-chip high-accuracy oscillator | ±1.0% accuracy over 1.8–5.5 V and -20 to +85°C; eliminates need for external crystal in cost-sensitive applications. |
| Integrated RTC with calendar/alarm | Supports 99-year calendar, alarm interrupt, and auto-correction; enables time-stamped logging without external RTC IC. |
| Background data flash rewrite (BGO) | Not applicable - R5F1016CASM#30 has no data flash memory; simplifies firmware update logic and reduces BOM count. |
| Multi-channel serial interface | 2 CSI (SPI), 2 UART/LIN, 3 I²C channels share minimal pins; supports concurrent communication with sensors, displays, and host controllers. |

FAQ
What is the maximum operating frequency of the R5F1016CASM#30?
The R5F1016CASM#30 operates at up to 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation.
Does the R5F1016CASM#30 include data flash memory?
No, the R5F1016CASM#30 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates data flash is omitted. This simplifies firmware design by removing background rewrite requirements and flash library dependencies, making it ideal for fixed-parameter applications.
What package type and pin count does the R5F1016CASM#30 use?
The R5F1016CASM#30 uses a 30-pin plastic LSSOP package (7.62 mm body width, 0.65-mm lead pitch), designated by the "ASM" suffix and confirmed in Table 1-1 of the RL78/G13 datasheet. It is compatible with standard surface-mount reflow profiles and supports manual soldering for prototyping.
Which serial interfaces are available on the R5F1016CASM#30?
The R5F1016CASM#30 provides two CSI (SPI-compatible) channels, two UART/LIN channels, and three I²C/Simplified I²C channels. These interfaces are multiplexed across dedicated pins and support simultaneous operation - for example, UART for host communication and I²C for sensor reading - without resource conflict.
Is the R5F1016CASM#30 qualified for industrial temperature range?
Yes, the R5F1016CASM#30 is rated for -40°C to +85°C operation (Industrial grade "D" variant), as indicated by the "D" in the ordering code structure and confirmed in the RL78/G13 datasheet Section 1.1.
