Overview
R5F12017MSP#70 from Renesas Electronics is a 10-pin LSSOP packaged RL78/G15 16-bit microcontroller with 4 KB code flash, 1 KB RAM, and 1 KB data flash, operating from 2.4 V to 5.5 V across −40°C to +125°C industrial temperature range. It integrates an 8-channel 16-bit timer array, 4-channel 8/10-bit A/D converter, UART, two simplified I²C interfaces, and on-chip debug - targeting compact embedded control in motor drives, sensor nodes, and industrial HMI.
For engineers reviewing the R5F12017MSP#70 datasheet, R5F12017MSP#70 pinout, R5F12017MSP#70 application, or R5F12017MSP#70 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use scenarios, and validated alternative options for design-in and supply continuity planning.
Technical Context
The R5F12017MSP#70 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution time of 0.0625 μs at 16 MHz (high-speed on-chip oscillator) or 1.0 μs at 1 MHz (low-speed mode). Its memory subsystem includes 4 KB code flash (1 KB block erase), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 1 KB SRAM.
Peripherals include one UART channel, two simplified I²C channels, one simplified SPI (CSI) channel, 4 analog inputs (ANI0–ANI3), one comparator (IVCMP0), programmable clock/buzzer output (PCLBUZ0), and 8 vectored interrupt sources (INTP0–INTP7) - all mapped to its 10-pin LSSOP footprint with VDD/VSS, RESET, and TOOL interface pins.

FAQ
What is the maximum operating frequency of the R5F12017MSP#70?
The R5F12017MSP#70 supports a maximum high-speed on-chip oscillator frequency of 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. It also supports external crystal (X1/X2) or EXCLK input up to 12 MHz, though the R5F12017MSP#70 variant does not include X1/X2 pins - limiting it to on-chip oscillator or EXCLK-only clocking.
Does the R5F12017MSP#70 support crystal oscillator connection?
No, the R5F12017MSP#70 in its 10-pin LSSOP package lacks X1 and X2 pins required for crystal oscillator connection. It relies exclusively on the high-speed on-chip oscillator (1–16 MHz) or external clock input via EXCLK (if routed externally), as confirmed by the pin configuration table for 10-pin products in the R01DS0420EJ0140 datasheet.
How many analog input channels does the R5F12017MSP#70 provide?
The R5F12017MSP#70 provides four analog input channels: ANI0, ANI1, ANI2, and ANI3 - mapped to pins P01, P02, P03, and P04 respectively. This matches the "4 channels" specification for 10-pin RL78/G15 devices in Table 1-6 of the datasheet, and supports simultaneous sampling via the 8/10-bit A/D converter.
What is the data flash endurance specification for the R5F12017MSP#70?
The R5F12017MSP#70 features 1 KB of data flash memory rated for 1,000,000 write/erase cycles (typical), with 512-byte block erase granularity and 32-bit rewrite units. Rewrites require VDD = 2.4–5.5 V and do not support background operation - code execution halts during data flash programming.
Is the R5F12017MSP#70 pin-compatible with other RL78/G15 10-pin variants?
Yes, the R5F12017MSP#70 shares identical pinout and package (10-pin LSSOP) with R5F12018MSP#70, R5F12017ASP#70, and R5F12017GSP#70. All 10-pin RL78/G15 devices use the same multiplexed function mapping per Table 1-3, enabling direct substitution where flash size or temperature grade permits.
