FAQ
What is the maximum operating frequency of the UPD78F1144AGB(R)-GAH-AX?
The UPD78F1144AGB(R)-GAH-AX operates at a maximum CPU frequency of 20 MHz with a 1.8–5.5 V supply. Its internal PLL allows clock multiplication from external crystal or ceramic resonator inputs, enabling stable 20 MHz operation even with low-cost 4 MHz or 8 MHz crystals. This frequency is fully supported across the full industrial temperature range without derating.
Does the UPD78F1144AGB(R)-GAH-AX support in-system programming (ISP)?
Yes, the UPD78F1144AGB(R)-GAH-AX supports in-system programming via its on-chip bootloader using UART0. No external high-voltage programmer is required-field firmware updates can be performed using standard 3.3 V logic-level serial communication. The UPD78F1144AGB(R)-GAH-AX retains full ISP capability even after security lock bits are set, provided the correct unlock sequence is implemented in host firmware.
What development tools are officially supported for the UPD78F1144AGB(R)-GAH-AX?
Renesas officially supports the UPD78F1144AGB(R)-GAH-AX with the RA78K0R Assembler Package (Ver. 1.20), CC78K0R C Compiler (Ver. 2.00), QB-MINI2 on-chip debug emulator, and SM+ System Simulator. These tools are documented in Renesas User's Manual U17854EJ9V0UD and verified for full peripheral register access, real-time debugging, and Flash programming of the UPD78F1144AGB(R)-GAH-AX.
Is the UPD78F1144AGB(R)-GAH-AX qualified for automotive applications?
No, the UPD78F1144AGB(R)-GAH-AX is rated as a Standard quality grade device per Renesas documentation and is intended for industrial, office, and consumer applications-not automotive. It does not meet AEC-Q100 stress test requirements. For automotive use, Renesas recommends the RL78/F13 or RH850/F1L families, which carry explicit AEC-Q100 qualification and extended temperature support.
How many ADC channels can be scanned in hardware-triggered sequence mode on the UPD78F1144AGB(R)-GAH-AX?
The UPD78F1144AGB(R)-GAH-AX supports hardware-triggered sequential conversion across up to 24 ADC input channels using its built-in scan mode. Trigger sources include internal timers (TMM0, TMM1), external pins (INTP0–INTP3), or software commands. Each channel's sampling time and conversion order are configurable via dedicated SFRs, eliminating CPU intervention during acquisition.
