Product details
Overview
R5F1016CASP#10 from Renesas is a 20-pin, 16 KB flash, 2 KB RAM RL78/G13 16-bit microcontroller with data flash disabled, operating at 1.6–5.5 V and rated for -40°C to +85°C industrial use. It delivers 41 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (6 channels), RTC calendar, and UART/SPI/I²C interfaces - deployed in battery-powered sensor nodes and smart metering front-ends.
For engineers reviewing the R5F1016CASP#10 datasheet, R5F1016CASP#10 pinout, R5F1016CASP#10 application, or R5F1016CASP#10 equivalent, key selection criteria include its 20-pin LSSOP package, absence of on-chip data flash, 6-channel analog input capability, real-time clock with alarm, and support for LIN-bus via UART - critical for cost-sensitive, low-power embedded control designs.
Technical Context
The R5F1016CASP#10 implements the RL78 CPU core with 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 includes 1 MB address space, 16 KB code flash organized in 1 KB blocks, and 2 KB on-chip RAM - all accessible under single-supply operation from 1.6 V.
Power management integrates on-chip POR and 14-level LVD with interrupt/reset selection, while peripherals include 8× 16-bit timers, 1× 12-bit interval timer, 1× watchdog timer (dedicated low-speed oscillator), and DMA controller with 2 channels - enabling deterministic real-time response in resource-constrained systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006CASP#10 | Includes 4 KB data flash memory; otherwise identical flash/RAM/peripheral set and pinout | Required where field firmware updates or parameter storage (e.g., calibration data) must persist across power cycles | Select R5F1006CASP#10 if nonvolatile parameter storage is needed; R5F1016CASP#10 saves cost where data flash is unused |
| STM8L052C6T6 | 8-bit STM8 core, 32 KB flash, 2 KB RAM, 12-bit ADC (16 ch), 1.65–3.6 V supply, -40°C to +85°C | Better ADC resolution and channel count, but lacks RTC calendar and LIN support; lower DMIPS (16 MHz max) | Choose STM8L052C6T6 for higher-resolution analog acquisition in 3.3 V-only systems; R5F1016CASP#10 preferred for LIN communication or calendar-aware scheduling |
Compared with R5F1006CASP#10, R5F1016CASP#10 removes data flash to reduce cost and die size while retaining identical code flash, RAM, and peripheral functionality - making it optimal for fixed-function firmware. Against STM8L052C6T6, it trades ADC resolution for 16-bit performance, LIN capability, and richer timer/RTC features essential in time-coordinated embedded systems.

FAQ
Does R5F1016CASP#10 include on-chip data flash memory?
No, R5F1016CASP#10 does not include data flash memory. The "1" in the second digit of the part number (R5F1016C…) explicitly indicates data flash is omitted. This distinguishes it from R5F1006CASP#10, which includes 4 KB of data flash. All other memory and peripheral specifications - including 16 KB code flash and 2 KB RAM - are identical between the two variants.
What is the package type and pin count of R5F1016CASP#10?
R5F1016CASP#10 uses a 20-pin plastic LSSOP package (7.62 mm × 4.4 mm, 0.65-mm pitch), designated by the "SP" suffix and confirmed in Renesas' ordering matrix. It shares pinout compatibility with other 20-pin RL78/G13 variants in LSSOP and TSSOP packages, including identical signal mapping for P10, P11, P20–P22, and P147.
Can R5F1016CASP#10 operate from a 1.8 V supply?
Yes, R5F1016CASP#10 supports operation from 1.6 V to 5.5 V, fully covering 1.8 V nominal supply rails. At 1.8 V, it maintains full functionality including 10-bit ADC (with internal 1.45 V reference), RTC, and all serial interfaces - validated across the full industrial temperature range (-40°C to +85°C).
Does R5F1016CASP#10 support LIN bus communication?
Yes, R5F1016CASP#10 supports LIN bus communication through its UART peripheral. The UART module includes LIN-break detection, sync-field transmission, and checksum generation - compliant with LIN 2.2A specification. This capability is enabled in both R5F100x and R5F101x variants of the RL78/G13 family.
What debug interface does R5F1016CASP#10 provide?
R5F1016CASP#10 includes an on-chip debug interface compatible with Renesas E2 emulator and E2 studio IDE. Debug signals (TOOLRxD/TOOLTxD) are multiplexed on pins P11 and P12, enabling full SWD-like functionality including halt/resume, register inspection, and flash programming - without requiring additional debug hardware pins.
