Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1006AASM#50 | Includes 4 KB data flash; identical core, package, and peripherals | Required where non-volatile parameter storage (e.g., calibration data) must persist across resets | Select R5F1006AASM#50 when field-updatable configuration or error logging is needed; otherwise R5F1016AASM#50 reduces BOM cost |
| RL78/G14 R5F104BAASM#50 | Higher flash (64 KB), 32 KB RAM, enhanced DMA and USB support; same TSSOP-20 package | Suitable for designs anticipating firmware expansion or requiring USB device connectivity | Choose R5F104BAASM#50 if future feature growth or host-side USB integration is planned; R5F1016AASM#50 optimizes for cost-constrained, fixed-function deployments |
Compared with R5F1006AASM#50, the R5F1016AASM#50 saves cost by omitting data flash while retaining identical timing, power, and I/O capabilities; versus R5F104BAASM#50, it trades scalability and USB for lower unit price and smaller memory footprint - ideal for stable, volume production of resource-tight embedded controllers.

FAQ
What is the maximum operating frequency of the R5F1016AASM#50?
The R5F1016AASM#50 supports up to 32 MHz operation using its high-speed on-chip oscillator, delivering 41 DMIPS performance. It also supports ultra-low-speed operation down to 32.768 kHz for RTC and ultra-low-power modes - all within the same R5F1016AASM#50 device without external clock components.
Does the R5F1016AASM#50 include data flash memory?
No, the R5F1016AASM#50 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash; models with "100" (e.g., R5F1006AASM#50) include 4 KB. The R5F1016AASM#50 relies on code flash for both program and limited parameter storage, or external EEPROM for persistent data.
What debug interface does the R5F1016AASM#50 support?
The R5F1016AASM#50 supports on-chip debug via the TOOLRxD (P13) and TOOLTxD (P14) pins, enabling full in-circuit debugging and flash programming using Renesas E2 studio and E2 Lite emulator. No JTAG header or additional pins are required - the debug interface shares pins with external interrupts to preserve I/O count.
Can the R5F1016AASM#50 operate from a 1.8 V supply?
Yes, the R5F1016AASM#50 operates across 1.6 V to 5.5 V, making it fully compatible with 1.8 V logic rails. Its I/O ports support different-potential interfacing, allowing direct connection to 1.8 V, 2.5 V, or 3.3 V peripherals without level shifters - a key advantage confirmed in the R5F1016AASM#50 datasheet Section 1.1.
How many analog input channels are available on the R5F1016AASM#50?
The R5F1016AASM#50 provides six analog input channels (ANI0–ANI2 and ANI18 on P20, P21, P22, and P147), matching the full ADC capability of the RL78/G13 family in the 20-pin TSSOP package. All six channels are accessible and functional in the R5F1016AASM#50 without multiplexing limitations.
