Product details

Overview

R5F12048GSP#50 from Renesas Electronics is an 16-pin, 8 KB flash, 1 KB RAM RL78/G15 16-bit microcontroller for industrial applications (−40°C to +105°C), featuring a 16 MHz high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C), 7-channel 8/10-bit A/D converter, and 8-channel 16-bit timer array. It supports UART, two simplified I²C channels, and two simplified SPI (CSI) interfaces.

For engineers reviewing the R5F12048GSP#50 datasheet, R5F12048GSP#50 pinout, R5F12048GSP#50 application, or R5F12048GSP#50 equivalent, key selection criteria include its 16-pin SSOP package with 0.65-mm pitch, industrial temperature grade, integrated data flash (1 KB), on-chip debug support, and low-power HALT/STOP modes enabling battery-powered sensor nodes and motor control subsystems.

Technical Context

The R5F12048GSP#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, 1 MB address space, and selectable power-on-reset (SPOR) with four voltage thresholds. Its clock system integrates a high-speed on-chip oscillator (1–16 MHz), low-speed 15 kHz oscillator, and external crystal input (X1/X2, up to 12 MHz).

Peripheral integration includes an 8-channel TAU0 timer array supporting PWM outputs (up to 4 channels), dual serial array units (SAU0) enabling simultaneous UART + I²C + CSI operation, and a comparator with internal/external reference selection - all operating within VDD = 2.4–5.5 V across the full industrial temperature range.

FAQ

What is the maximum operating frequency and oscillator accuracy of the R5F12048GSP#50?

The R5F12048GSP#50 supports a maximum high-speed on-chip oscillator frequency of 16 MHz with ±1.0% accuracy over the temperature range of −20°C to +85°C. At full industrial grade (−40°C to +105°C), accuracy degrades to ±1.5% in the +85°C to +105°C sub-range. External crystal operation (X1/X2) supports up to 12 MHz with stability dependent on resonator selection and board layout.

Does the R5F12048GSP#50 support in-system programming and data retention during rewrites?

Yes, the R5F12048GSP#50 supports self-programming of both code and data flash memory without requiring external programming hardware. Data flash retains valid data during code flash erase/write operations. The data flash is rated for 1,000,000 rewrite cycles at VDD = 2.4–5.5 V, with 32-bit rewrite granularity and 512-byte block erase - enabling reliable parameter storage in field-deployed R5F12048GSP#50 systems.

How many analog input channels and what A/D resolution does the R5F12048GSP#50 provide?

The R5F12048GSP#50 integrates an 8/10-bit successive approximation A/D converter with 7 analog input channels (ANI0 through ANI6). Resolution is selectable per conversion, and the module supports internal reference voltage (0.815 V typical) or external reference. All 7 channels are accessible in the 16-pin SSOP package, matching the pin count and peripheral allocation specified for R5F12048GSP#50 in the RL78/G15 datasheet.

Can the R5F12048GSP#50 operate in ultra-low-power modes, and what are the key entry conditions?

Yes, the R5F12048GSP#50 supports HALT and STOP low-power modes. HALT mode stops the CPU clock while preserving RAM and register contents, drawing ~54 µA/MHz at 125°C. STOP mode halts all clocks including peripherals, reducing current to sub-µA levels. Entry requires writing to the stop control register (STPC) and executing a WAIT instruction. Wake-up sources include external interrupts (INTP0–INTP7), LVI reset, and watchdog timeout - all fully supported on R5F12048GSP#50.

What serial communication interfaces are available on the R5F12048GSP#50, and how are they allocated in the 16-pin SSOP package?

The R5F12048GSP#50 provides UART (1 channel), simplified I²C (2 channels), and simplified SPI (CSI, 2 channels) via its SAU0 serial array unit. In the 16-pin SSOP package, these map to dedicated pins: UART uses P00 (TxD0) and P01 (RxD0); I²C0 uses P02 (SCL00) and P04 (SDA00); I²C1 uses P06 (SCL01) and P07 (SDA01); CSI0 uses P02 (SCK00), P04 (SI00), and P05 (SO00); CSI1 uses P06 (SCK01), P07 (SI01), and P05 (SO01). All interfaces are functional on R5F12048GSP#50 without pin conflict.
