FAQ
What is the maximum operating frequency of the UPD78F1143AGB-GAH-M1-AX?
The UPD78F1143AGB-GAH-M1-AX operates at a maximum system clock frequency of 20 MHz. This rating is guaranteed across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V). The internal PLL allows flexible clock configuration from external crystal or ceramic resonator sources, and all timing specifications-including ADC conversion time and PWM resolution-are validated at this maximum frequency.
Does the UPD78F1143AGB-GAH-M1-AX support in-system programming?
Yes, the UPD78F1143AGB-GAH-M1-AX supports in-system programming via its on-chip bootloader. Firmware updates can be performed through the UART interface using Renesas' standard flash programming protocol, or via the single-wire debug (SWD) interface during development and field service. No external programmer is required for routine updates, and the bootloader occupies fixed 2 KB of Flash space reserved at the top of the memory map.
What is the ADC accuracy specification for the UPD78F1143AGB-GAH-M1-AX?
The UPD78F1143AGB-GAH-M1-AX features a 10-bit successive approximation ADC with ±1 LSB integral nonlinearity (INL) and ±0.5 LSB differential nonlinearity (DNL) over the full operating temperature and voltage range. Accuracy assumes proper decoupling of AVDD/AVSS, use of AVREF or internal 2.5 V reference, and adherence to recommended sampling time settings per channel. External reference inputs support 2.0–5.5 V for flexible scaling.
Is the UPD78F1143AGB-GAH-M1-AX pin-compatible with other 78K0R/KE3 microcontrollers?
Yes, the UPD78F1143AGB-GAH-M1-AX shares identical pinout and electrical characteristics with other members of the 78K0R/KE3 family in the 100-pin QFP package, including UPD78F1142AGB-GAH-M1-AX and UPD78F1144AGB-GAH-M1-AX. This enables direct PCB-level substitution where Flash size and peripheral requirements align, without layout modification or signal integrity revalidation.
What debug interface does the UPD78F1143AGB-GAH-M1-AX provide?
The UPD78F1143AGB-GAH-M1-AX provides a single-wire debug (SWD) interface compliant with Renesas' standard debug protocol. This interface supports full read/write access to CPU registers, memory, and peripheral control registers, along with hardware breakpoints, watchpoints, and real-time trace capabilities. Debug connection requires only two pins (SWDIO and SWCLK), minimizing I/O overhead compared to traditional JTAG implementations.
