It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial and consumer equipment.

For engineers reviewing the UPD78F1213GA-HAA-AX datasheet, UPD78F1213GA-HAA-AX pinout, UPD78F1213GA-HAA-AX application, or UPD78F1213GA-HAA-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), 12-bit ADC resolution with 16 input channels, 48-pin LQFP package, and support for on-chip debug via single-wire interface - all critical for cost-sensitive, space-constrained MCU designs requiring field firmware updates.

Technical Context

The UPD78F1213GA-HAA-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 12-bit successive-approximation ADC with sample-and-hold, programmable conversion timing, and hardware trigger sources from timers or external pins.

Peripheral subsystems include three 16-bit timer arrays (each with capture/compare/PWM functions), two UART channels with LIN support, one I²C interface with multimaster capability, and a watchdog timer with independent clock source. The device supports boot ROM-based self-programming and secure flash protection via lock bits.

Key Specifications

Pinout & Package

The UPD78F1213GA-HAA-AX is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad (EP) for enhanced heat dissipation in continuous operation. Pin numbering follows standard top-view convention with pin 1 marked by dot or notch.

FAQ

What is the maximum operating frequency of the UPD78F1213GA-HAA-AX?

The UPD78F1213GA-HAA-AX supports a maximum system clock frequency of 20 MHz using its on-chip PLL, with guaranteed operation up to 16 MHz across the full temperature and voltage range. This enables deterministic real-time execution of control algorithms while maintaining low EMI emissions due to the synchronous design of the 78K0R core. The UPD78F1213GA-HAA-AX achieves this performance with typical current consumption of 8.5 mA at 16 MHz and 3.3 V.

Does the UPD78F1213GA-HAA-AX support in-system programming?

Yes, the UPD78F1213GA-HAA-AX supports full in-system programming via its single-wire on-chip debug interface (OCDS), allowing firmware updates without removing the device from the target board. The UPD78F1213GA-HAA-AX uses SuperFlash® technology enabling 100,000 write/erase cycles and 10-year data retention - verified per Renesas qualification standards. Boot ROM routines handle flash erase/write sequencing and verify integrity post-write.

What analog input channels does the UPD78F1213GA-HAA-AX ADC support?

The UPD78F1213GA-HAA-AX integrates a 12-bit successive-approximation ADC with 16 selectable analog input channels mapped to P10–P17 and P20–P27 pins. These channels support differential and single-ended modes, hardware triggering from timers or external events, and built-in sample-and-hold. The UPD78F1213GA-HAA-AX ADC achieves ±1 LSB integral nonlinearity and supports conversion times as fast as 1.5 µs per channel under optimal conditions.

Is the UPD78F1213GA-HAA-AX pin-compatible with other 78K0R/IC3 devices?

No, the UPD78F1213GA-HAA-AX is not fully pin-compatible with other 78K0R/IC3 variants such as UPD78F1211 or UPD78F1215 due to differences in peripheral mapping and I/O function assignment - for example, P140/P141 are reserved for crystal oscillator in UPD78F1213GA-HAA-AX but serve as general I/O in UPD78F1211. The UPD78F1213GA-HAA-AX shares the same 48-pin LQFP package footprint but requires verification of pin function alignment per application schematic.

What debug tools are officially supported for the UPD78F1213GA-HAA-AX?

Renesas officially supports the QB-MINI2 on-chip debug emulator and ID78K0R-QB integrated debugger for the UPD78F1213GA-HAA-AX, enabling full-speed execution control, register inspection, flash programming, and real-time variable monitoring. The UPD78F1213GA-HAA-AX also works with RA78K0R assembler and CC78K0R C compiler toolchains. Debug access requires only the single-wire OCDS interface and no additional JTAG header.
