Product details
Overview
R5F1016EASP#V0 from Renesas is a 20-pin RL78/G13 16-bit microcontroller with 64 KB flash memory, 4 KB data flash, and 3 KB RAM, operating at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), integrated 10-bit ADC (26-channel), real-time clock, UART/SPI/I²C interfaces, and operates across –40°C to +85°C for industrial control and sensor node applications.
For engineers reviewing the R5F1016EASP#V0 datasheet, R5F1016EASP#V0 pinout, R5F1016EASP#V0 application, or R5F1016EASP#V0 equivalent, key selection criteria include its LSSOP-20 package, absence of on-chip data flash (R5F101x series), low-power HALT/STOP/SNOOZE modes, and support for self-programming with boot swap - critical for firmware-upgradable embedded systems with constrained power budgets.
Technical Context
The R5F1016EASP#V0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space, with dedicated SFRs enabling efficient peripheral control via bit-manipulation instructions.
Power management includes an on-chip POR circuit, 14-level voltage detector (LVD) with interrupt/reset options, and multiple low-power modes coordinated by the system clock controller. Peripheral integration includes a 16-bit timer array (8 channels), 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, and DMA controller supporting 2-channel transfers with 2-clock latency between SFR and RAM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and compact code size for resource-constrained firmware. |
| Max Operating Frequency | 32 MHz; delivers 41 DMIPS performance suitable for real-time motor control and protocol stack execution. |
| Flash Memory | 64 KB code flash with 1 KB block size; supports secure erase prohibition and in-application programming (IAP). |
| Data Flash | None (R5F101x series); eliminates data retention overhead but requires external EEPROM or FRAM for nonvolatile parameter storage. |

Pinout & Package
Package: 20-pin plastic LSSOP (7.62 mm, 0.65-mm pitch), JEDEC MS-013AC compliant, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | SPI Clock / I²C Clock | Dual-function pin enabling shared PCB routing for SPI sensors or I²C peripherals; requires software-configurable mode selection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006EASP#V0 | Includes 4 KB on-chip data flash; otherwise identical flash/RAM/peripherals/package. | Preferred where firmware must store calibration data, device IDs, or usage logs without external memory. | Select R5F1006EASP#V0 if nonvolatile parameter storage is required; R5F1016EASP#V0 reduces cost and complexity when external EEPROM suffices. |
| RL78/G14 R5F104G8ASP#V0 | Higher integration: 128 KB flash, 12 KB RAM, 32 KB data flash, enhanced ADC (12-bit, 32 ch), and CAN 2.0B interface. | Targets more complex systems requiring CAN bus connectivity, larger code footprint, or higher-resolution analog acquisition. | Choose RL78/G14 only if CAN or >64 KB flash is mandatory; R5F1016EASP#V0 offers optimal cost/power balance for simpler control tasks. |
Compared with R5F1006EASP#V0, R5F1016EASP#V0 removes data flash to lower unit cost and power, while retaining identical code density and peripheral set; versus RL78/G14, it trades CAN and memory headroom for significantly lower static current and smaller footprint - making it ideal for cost-sensitive, battery-powered endpoints.

FAQ
What is the maximum clock frequency supported by the R5F1016EASP#V0?
The R5F1016EASP#V0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator, achieving 41 DMIPS performance. This frequency is fully rated across the full industrial temperature range (–40°C to +85°C) and 1.6–5.5 V supply, enabling deterministic real-time response in motor control and protocol processing tasks without external crystal dependency.
Does the R5F1016EASP#V0 include on-chip data flash memory?
No, the R5F1016EASP#V0 does not include on-chip data flash memory. As indicated by the "101" prefix in its part number per Renesas documentation, this variant belongs to the data-flash-less RL78/G13 series. Designers requiring nonvolatile parameter storage must use external EEPROM, FRAM, or rely on code flash sectors configured for data emulation - unlike the R5F1006EASP#V0 which integrates 4 KB of dedicated data flash.
What package type and pin count does the R5F1016EASP#V0 use?
The R5F1016EASP#V0 uses a 20-pin plastic LSSOP (7.62 mm, 0.65-mm pitch) package, identified by the "SP" suffix and "#V0" tray packaging code. This JEDEC-standard package provides surface-mount compatibility, thermal performance suitable for industrial ambient temperatures, and pin spacing that supports automated assembly without solder bridging risks.
Which low-power modes are available on the R5F1016EASP#V0?
The R5F1016EASP#V0 supports HALT, STOP, and SNOOZE low-power modes. HALT stops the main clock while preserving RAM and register contents; STOP disables all clocks including subsystem clocks for minimum current draw (0.57 μA with RTC+LVD active); SNOOZE allows selected peripherals like UART or ADC to operate asynchronously during reduced CPU activity - enabling responsive wake-up with minimal energy penalty.
Can the R5F1016EASP#V0 be programmed in-system via its serial interfaces?
Yes, the R5F1016EASP#V0 supports in-system programming (ISP) via its UART interface using Renesas' standard flash programming protocol. The on-chip debug function and boot swap capability allow firmware updates without removing the device from the board, and the self-programming library enables secure, verified writes to code flash - essential for remote maintenance of deployed R5F1016EASP#V0-based systems.
