Product details
Overview
R5F11W67ASM#30 from Renesas is an ultra-low-power 16-bit RL78/G1M microcontroller in a 20-pin TSSOP package, featuring 4 KB flash memory, 512 B RAM, 8-channel 8/10-bit ADC, 4-channel 16-bit timer, UART/CSI serial interfaces, and operation from 2.25–5.5 V at –40 to +85°C. It targets battery-powered consumer control systems requiring compact size and deterministic real-time response.
For engineers reviewing the R5F11W67ASM#30 datasheet, R5F11W67ASM#30 pinout, R5F11W67ASM#30 application, or R5F11W67ASM#30 equivalent, key selection criteria include its 4 KB flash capacity, TSSOP-20 footprint, 20 MHz high-speed on-chip oscillator (±2% accuracy), HALT/STOP low-power modes, and integrated key interrupt and buzzer output functions for cost-sensitive embedded control.
Technical Context
The R5F11W67ASM#30 implements the RL78-S1 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.05 µs (20 MHz) to 0.8 µs (1 MHz). Its peripheral set includes a 4-channel TAU timer unit with PWM-capable outputs, a 12-bit interval timer, and watchdog timer operating from the dedicated 15 kHz low-speed oscillator.
It integrates a programmable clock/buzzer output (PCLBUZ0), on-chip debug support, selectable power-on-reset (SPOR) with four detection thresholds (2.25/2.68/3.02/4.45 V), and configurable I/O with N-ch open-drain (14 pins) and P-ch open-drain (6 pins) options - all within a single 20-pin TSSOP package optimized for space-constrained designs.

FAQ
What is the maximum operating frequency of the R5F11W67ASM#30?
The R5F11W67ASM#30 supports a maximum high-speed on-chip oscillator frequency of 20 MHz, delivering a minimum instruction execution time of 0.05 µs under 2.7–5.5 V supply conditions. This frequency is selectable via option byte settings and does not require an external crystal, simplifying BOM and layout for timing-tolerant applications.
Does the R5F11W67ASM#30 include an integrated ADC?
Yes, the R5F11W67ASM#30 integrates an 8/10-bit resolution A/D converter with 8 analog input channels (ANI0–ANI7), operating over a 2.4–5.5 V reference range. It supports single- or continuous-conversion modes and can be triggered by software, timer, or external events - enabling direct sensor interfacing without external signal conditioning.
What low-power modes does the R5F11W67ASM#30 support?
The R5F11W67ASM#30 supports HALT mode (390–980 µA at 3–5 V) and STOP mode (0.61–2.35 µA at 3 V), both retaining RAM content and allowing wake-up via external interrupts, timer events, or key return inputs. These modes are critical for extending battery life in intermittently active devices like remote controls and environmental sensors.
Is the R5F11W67ASM#30 pin-compatible with other RL78/G1M devices?
Yes, the R5F11W67ASM#30 shares the same 20-pin TSSOP package and pin configuration with other RL78/G1M variants including R5F11W68ASM#30 and R5F11Y67ASM#30. Pin functions are consistent across the family, enabling hardware reuse when upgrading flash size or selecting G1N for higher drive strength - provided peripheral register initialization matches the target device.
What debug capabilities does the R5F11W67ASM#30 provide?
The R5F11W67ASM#30 includes an on-chip debug function accessible via the TOOL0 pin, supporting full-featured emulation, breakpoint setting, and flash programming without external hardware. This capability accelerates firmware development and field updates but is not recommended for mass-production use due to flash endurance limitations.
