FAQ
What is the maximum operating frequency of the R5F1214CASP#30?
The R5F1214CASP#30 supports a maximum system clock of 16 MHz using its high-speed on-chip oscillator. Instruction execution time can be as fast as 0.0625 μs at this frequency. External crystal oscillators up to 20 MHz are also supported via X1/X2 pins for higher-precision timing requirements.
Does the R5F1214CASP#30 support background data flash programming?
No, the R5F1214CASP#30 does not support background operation (BGO) for data flash. During data flash rewriting, instruction execution from code flash memory is suspended. This requires careful firmware design to avoid real-time task interruption during non-volatile parameter updates.
What touch sensing methods does the CTSU in R5F1214CASP#30 support?
The R5F1214CASP#30's capacitive touch sensing unit supports both self-capacitance (single-pin per key, up to 15 keys) and mutual-capacitance (matrix configuration using transmit/receive pin pairs, up to 16 keys). Both modes operate with hardware acceleration and built-in noise rejection.
Is the R5F1214CASP#30 pin-compatible with other RL78/G16 variants in SSOP package?
Yes, the R5F1214CASP#30 shares identical pinout and electrical characteristics with other 16-pin SSOP RL78/G16 parts including R5F1214AASP#30 and R5F1214CGSP#30. Firmware and PCB layout are interchangeable across these variants, enabling seamless memory or grade upgrades.
What is the guaranteed data retention period for the data flash in R5F1214CASP#30?
The data flash in the R5F1214CASP#30 guarantees 1,000,000 write/erase cycles (typical) and data retention of 20 years at +85°C ambient temperature. Retention is extended at lower temperatures, supporting long-life industrial deployments with infrequent parameter updates.
