FAQ

What is the maximum operating frequency of the UPD78F1822AGBA-GAH-E2-G?

The UPD78F1822AGBA-GAH-E2-G supports a maximum CPU operating frequency of 20 MHz using its on-chip PLL. Without PLL, the maximum frequency is 16 MHz when driven by the main system clock. This timing specification is validated across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V). The UPD78F1822AGBA-GAH-E2-G achieves consistent instruction throughput under these conditions due to its zero-wait-state Flash memory access architecture.

Does the UPD78F1822AGBA-GAH-E2-G support in-system programming (ISP)?

Yes, the UPD78F1822AGBA-GAH-E2-G supports in-system programming via its on-chip boot ROM and the Renesas Flash Self-Programming Library Type02. Firmware updates can be performed through UART or CSI interfaces without removing the device from the target board. The UPD78F1822AGBA-GAH-E2-G requires no external high-voltage programming signal - all necessary voltages are generated internally during programming sequences.

What analog peripherals are integrated into the UPD78F1822AGBA-GAH-E2-G?

UPD78F1822AGBA-GAH-E2-G integrates a 10-bit successive-approximation ADC with 16 input channels and a conversion time of 1.2 μs, two independent 8-bit D/A converters with simultaneous update capability, and an internal 2.5 V reference voltage source. These analog resources are electrically isolated from digital noise sources via separate AVDD/AVSS domains and dedicated AVREF pin - enabling precision signal acquisition and generation without external components.

Is the UPD78F1822AGBA-GAH-E2-G pin-compatible with other 78K0R/FE3 devices?

No, the UPD78F1822AGBA-GAH-E2-G is not universally pin-compatible across the 78K0R/FE3 family. While it shares the same 64-pin LQFP (GBA) package with other FE3 variants like UPD78F1821 and UPD78F1831, pin functions differ significantly - especially for peripheral mapping (e.g., UART channel assignment, ADC channel routing, and timer output locations). Board-level compatibility must be verified per specific variant using the Renesas Hardware User's Manual Rev.6.00.

What debug interface does the UPD78F1822AGBA-GAH-E2-G support?

The UPD78F1822AGBA-GAH-E2-G supports single-wire debug (SWD) via the dedicated BKGD pin, enabling full-featured on-chip debugging including breakpoints, watchpoints, register inspection, and memory read/write. This interface requires only one physical signal plus ground, eliminating the need for JTAG cabling. Debug functionality is accessible throughout all low-power modes except deep STOP, and remains active during Flash programming operations of the UPD78F1822AGBA-GAH-E2-G.
