Overview
R5F1214AGSP#50 from Renesas Electronics is a 16-pin, 32 KB flash, 2 KB RAM RL78/G16 16-bit microcontroller with integrated capacitive touch sensing (15-channel CTSU), 10-bit A/D converter (11 channels), real-time clock (99-year calendar), and low-power STOP/HALT modes. It operates from 2.4 to 5.5 V and supports industrial temperature range (−40°C to +105°C), targeting embedded control in appliance user interfaces and industrial HMI panels.
For engineers reviewing the R5F1214AGSP#50 datasheet, R5F1214AGSP#50 pinout, R5F1214AGSP#50 application, or R5F1214AGSP#50 equivalent, key selection criteria include its 16-pin SSOP package, G-grade industrial qualification, 32 KB code flash with self-programming, 10-bit ADC with internal reference, and hardware CTSU supporting up to 16 keys in mutual-capacitance mode.
Technical Context
The R5F1214AGSP#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling instruction execution times from 0.0625 μs (16 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 32 KB on-chip code flash (1 KB block size), 1 KB data flash (512 B blocks, 1M rewrite cycles), and 2 KB RAM.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, watchdog timer, RTC2 with alarm and correction, simplified SPI/UART/I²C (up to 3 channels each), I²C master/slave, comparator (2 channels), and dedicated CTSU hardware supporting both self- and mutual-capacitance configurations without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1214CGSP#50 | Same package and pinout; C-grade (32 KB flash) but consumer temp range (−40°C to +85°C) | Suitable for cost-sensitive consumer appliances without extended temperature needs | Select when industrial temperature range is not required and lower qualification cost is prioritized |
| R5F1214AMSP#50 | Same package and pinout; A-grade (16 KB flash), M-grade temp (−40°C to +125°C) | Targeted at under-hood automotive or high-temp industrial environments with reduced code density needs | Choose when +125°C operation is mandatory and 16 KB flash suffices for application firmware |
Compared with R5F1214AGSP#50, R5F1214CGSP#50 trades industrial temperature qualification for identical performance at lower cost, while R5F1214AMSP#50 extends thermal range to +125°C but halves flash capacity - guiding selection based on environmental and firmware size constraints.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R5F1214AGSP#50?
The R5F1214AGSP#50 supports a high-speed on-chip oscillator up to 16 MHz, delivering a minimum instruction execution time of 0.0625 μs. This timing is achievable with the high-speed on-chip oscillator enabled and no wait states - verified in the R01DS0431EJ0130 datasheet Section 1.1. The core maintains full functionality across all supported frequencies including 32.768 kHz for ultra-low-power RTC operation.
Does the R5F1214AGSP#50 support background data flash rewriting while executing code from main flash?
No, the R5F1214AGSP#50 does not support background operation (BGO) for data flash. As stated in the datasheet Section 1.1, instructions cannot be executed from code flash memory while rewriting data flash. Code execution must be halted or relocated to RAM during data flash write operations - a constraint confirmed in R01DS0431EJ0130 Rev.1.30 page 1.
How many capacitive touch channels does the R5F1214AGSP#50 support, and what configuration options are available?
The R5F1214AGSP#50 integrates a hardware Capacitive Touch Sensing Unit (CTSU) supporting 15 channels. It enables self-capacitance mode (1 key per pin, up to 15 keys) and mutual-capacitance mode (matrix configuration using transmit/receive pin selection from the same 15 pins, supporting up to 16 keys) - details confirmed in Section 1.1 "Capacitive touch sensing unit (CTSUb)" of R01DS0431EJ0130.
What is the package type and pin count of the R5F1214AGSP#50, and is it RoHS compliant?
The R5F1214AGSP#50 uses a 16-pin plastic SSOP package (4.4 × 5.0 mm, 0.65-mm pitch), as defined by the "SP" suffix in the part number and confirmed in Table 1-1 of R01DS0431EJ0130. It is RoHS-compliant and lead-free, consistent with Renesas' standard packaging specifications for industrial-grade products.
What are the key differences between the G-grade and M-grade variants of the R5F1214AGSP#50 family?
The G-grade (e.g., R5F1214AGSP#50) is rated for −40°C to +105°C operation, while the M-grade (e.g., R5F1214AMSP#50) extends to −40°C to +125°C. Both share identical pinout and peripherals, but M-grade units undergo additional screening for higher-temperature reliability - a distinction explicitly defined in Figure 1-1 and Table 1-1 of R01DS0431EJ0130.
