Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006CASM#70 | Includes 4 KB data flash; identical code flash (16 KB), RAM (2 KB), package, and peripherals. | Required where EEPROM-like nonvolatile parameter storage (e.g., calibration data, device ID) is needed without external memory. | Select R5F1006CASM#70 when field-updatable configuration persistence is mandatory; otherwise R5F1016CASM#70 reduces cost and flash wear. |
| RL78/G14 R5F104GCAFP#50 | 44-pin LQFP, 48 KB flash, 4 KB RAM, adds CAN 2.0B interface and enhanced DMA; no STOP-mode current specified below 1 μA. | Suitable for automotive body electronics or industrial networks requiring CAN bus integration and higher memory headroom. | Choose RL78/G14 only when CAN interface or >2 KB RAM is essential; R5F1016CASM#70 remains optimal for space-constrained, ultra-low-power TSSOP designs. |
Compared with R5F1006CASM#70, the R5F1016CASM#70 removes data flash to lower cost and simplify firmware update logic, while matching all timing, I/O, and low-power specs; versus RL78/G14, it trades CAN and memory for smaller footprint and proven sub-1 μA STOP current - critical for long-life portable devices.

FAQ
Does R5F1016CASM#70 include data flash memory?
No, R5F1016CASM#70 does not include data flash memory. It provides 16 KB of code flash and 2 KB of RAM only. Data flash is present in the R5F100x variant series (e.g., R5F1006CASM#70), but omitted in R5F101x parts to reduce cost and simplify firmware design for applications that store parameters in external EEPROM or use flash emulation techniques.
What is the minimum supply voltage for R5F1016CASM#70 operation?
The R5F1016CASM#70 operates down to 1.6 V across its full temperature range (–40°C to +85°C). This enables direct compatibility with single-cell lithium batteries (e.g., LiFePO₄ nominal 3.2 V, discharged to ~2.0 V) and legacy 1.8 V logic domains without level-shifting circuitry.
Can R5F1016CASM#70 support LIN bus communication?
Yes, R5F1016CASM#70 supports LIN 2.0/2.1/2.2 protocols via its UART peripheral with built-in LIN break detection and sync field generation. The UART module handles automatic checksum calculation and response timing - eliminating software overhead for LIN slave node implementation.
Is an external crystal required for accurate timing on R5F1016CASM#70?
No, R5F1016CASM#70 includes a high-accuracy on-chip oscillator (±1.0% over 1.8–5.5 V and –20 to +85°C), making external crystals unnecessary for UART, LIN, and RTC applications. An external crystal is optional only if tighter timing tolerance (<±0.5%) is required for specific protocol compliance.
What debug interface does R5F1016CASM#70 support?
R5F1016CASM#70 supports Renesas' on-chip debug interface via SWD (Serial Wire Debug) using dedicated TOOLRxD/TOOLTxD/TOOLCLK pins (P11/P12/P13). It enables full JTAG-style debugging - including breakpoints, watchpoints, and memory inspection - without requiring additional debug hardware beyond a standard E2 emulator or J-Link probe.
How many ADC channels are accessible on the 20-pin TSSOP package of R5F1016CASM#70?
The R5F1016CASM#70 in TSSOP-20 exposes 6 ADC input channels: ANI0 (P20), ANI1 (P21), ANI2 (P22), ANI18 (P147), plus ANI3 and ANI4 mapped to P10 and P11 when configured as analog inputs - confirmed in the RL78/G13 pin function table for 20-pin variants.
