Product details
Overview
R5F11Y67ASM#30 from Renesas Electronics is an ultra-low-power 16-bit RL78/G1N microcontroller in a 20-pin TSSOP package, featuring 4 KB flash memory, 512 B RAM, 8-channel 8/10-bit A/D converter, 1 UART, 1 CSI, 4-channel 16-bit timer, and watchdog timer - deployed in battery-powered consumer sensor nodes requiring compact size and extended runtime.
For engineers reviewing the R5F11Y67ASM#30 datasheet, R5F11Y67ASM#30 pinout, R5F11Y67ASM#30 application, or R5F11Y67ASM#30 equivalent, key selection criteria include its 20-pin TSSOP footprint, 4 KB flash/512 B RAM configuration, -40°C to +85°C industrial temperature grade, VDD = 2.0–5.5 V operation, and RL78/G1N-specific high-current P-ch open-drain I/O capability on P00–P05 pins.
Technical Context
The R5F11Y67ASM#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.05 µs at 20 MHz (high-speed on-chip oscillator) and 1.0 µs at 1 MHz (low-speed mode). It integrates selectable power-on-reset (SPOR) with four detection voltage options (2.25 V to 4.45 V) and operates across VDD = 2.0–5.5 V with mandatory use within 2.25–5.5 V due to SPOR threshold constraints.
This device belongs to the RL78/G1N group (denoted by "Y" in part number), distinguishing it from G1M with enhanced P-ch open-drain output capability on P00–P05 (–120 mA per pin at VDD = 4.5–5.5 V), absence of real-time output (RTIO) channels, and optimized peripheral I/O mapping for segment-com driver applications - confirmed via Pin Configuration (1.3.2) and Function Outline (1.6) in R01DS0378EJ0100 Rev.1.00.
Key Specifications

Pinout & Package
Package: 20-pin plastic TSSOP (4.4 × 6.5 mm, 0.65 mm pitch), RoHS-compliant, tray-packaged (#30 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum operating frequency and instruction execution time of the R5F11Y67ASM#30?
The R5F11Y67ASM#30 supports a high-speed on-chip oscillator up to 20 MHz, enabling a minimum instruction execution time of 0.05 µs under VDD ≥ 2.7 V. At lower VDD (2.0–2.7 V), the max frequency drops to 5 MHz with 0.2 µs minimum cycle time. The RL78 CPU core uses a 3-stage pipeline to maintain deterministic timing across all operating conditions, and the R5F11Y67ASM#30 maintains full functionality across its specified VDD and temperature range.
Does the R5F11Y67ASM#30 support hardware debugging and in-system programming?
Yes, the R5F11Y67ASM#30 includes an on-chip debug function accessible via the TOOL0 pin, enabling full in-circuit debugging, flash programming, and real-time trace without external JTAG adapters. This capability is documented in Section 1.1 and Section 2.1 of R01DS0378EJ0100 Rev.1.00. However, Renesas advises against using the debug function in mass-produced end products due to flash endurance limitations - the R5F11Y67ASM#30 must be programmed during manufacturing and operated in production mode thereafter.
What are the key differences between R5F11Y67ASM#30 and R5F11W67ASM#30?
The R5F11Y67ASM#30 is an RL78/G1N device with P-ch open-drain outputs on P00–P05 (–120 mA per pin), while R5F11W67ASM#30 is an RL78/G1M device offering real-time output (RTIO0–RTIO7) but lacking high-current P-ch drive. Both share 4 KB flash, 512 B RAM, and 20-pin TSSOP packaging, but their peripheral mappings differ - for example, P16 on R5F11Y67ASM#30 supports TxD0, whereas on R5F11W67ASM#30 it does not. Thus, R5F11Y67ASM#30 is not pin-compatible with R5F11W67ASM#30 for P-ch I/O applications.
Can the R5F11Y67ASM#30 operate from a single 3.0 V lithium coin cell?
Yes, the R5F11Y67ASM#30 operates across VDD = 2.0–5.5 V and is explicitly rated for 3.0 V operation in HALT and STOP modes, drawing as little as 300 µA (HALT) and 0.61 µA (STOP, typical at 25°C). Its selectable SPOR circuit includes a 2.25 V threshold option, ensuring reliable reset as the coin cell discharges below 2.5 V. The R5F11Y67ASM#30 also supports low-voltage ADC operation down to VDD = 2.4 V, making it suitable for long-life battery-powered designs.
What serial interface protocols does the R5F11Y67ASM#30 support?
The R5F11Y67ASM#30 integrates one UART channel (supporting asynchronous communication up to 3.3 Mbps theoretical rate at 20 MHz) and one CSI channel configurable as SPI master or slave. The UART supports standard framing (start/stop bits, parity), while CSI supports clock polarity/phase control (CKP/DAP bits) and variable SCK timing for interoperability with diverse peripherals. Neither interface requires external level shifters or protocol accelerators - the R5F11Y67ASM#30 handles all framing, clock generation, and data buffering in hardware.
