Product details
Overview
UPD78F0884AGAA2-GAM-G from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/Fx2 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and a maximum operating frequency of 20 MHz. It integrates a 10-bit A/D converter with 16 channels, UART, I²C, and 16-bit timer arrays, and targets industrial control and sensor interface applications.
For engineers reviewing the UPD78F0884AGAA2-GAM-G datasheet, UPD78F0884AGAA2-GAM-G pinout, UPD78F0884AGAA2-GAM-G application, or UPD78F0884AGAA2-GAM-G equivalent, this page delivers verified functional identity, package mapping (LQFP-100), confirmed peripheral set, real-world use context, and two validated alternative parts for design continuity.
Technical Context
The UPD78F0884AGAA2-GAM-G implements the 78K0 CPU core with 16-bit addressing and supports both standard and expanded-specification features including reduced A/D conversion time (1.1 μs typical) and enhanced flash endurance (100,000 write/erase cycles). It operates from 2.7 V to 5.5 V and includes on-chip voltage regulator (REGC pin) for internal logic supply stabilization.
It supports multiple low-power modes (HALT, STOP, and IDLE), features 16 interrupt sources with priority control, and provides dedicated hardware for serial communication (UART0/1, I²C bus interface) and precise timing (16-bit timer arrays TAU0/1 with capture/compare/PWM functions).

This clock speed supports real-time execution of control algorithms, such as motor commutation and PID loops, with predictable interrupt latency and instruction throughput consistent with the 78K0 CPU architecture.
Does the UPD78F0884AGAA2-GAM-G include an on-chip voltage regulator?
Yes, the UPD78F0884AGAA2-GAM-G includes an on-chip voltage regulator controlled by the REGC pin. When enabled, it generates a stable 3.3 V supply for internal logic from VDD ≥ 4.0 V, eliminating the need for an external LDO in many single-rail designs and reducing BOM count and board area.
How many analog-to-digital converter channels does the UPD78F0884AGAA2-GAM-G support?
The UPD78F0884AGAA2-GAM-G integrates a 10-bit successive-approximation A/D converter with 16 input channels. These channels can be configured for single-ended or differential measurement, and the converter achieves a typical conversion time of 1.1 μs - enabling high-speed sampling for current sensing, temperature monitoring, and other real-time analog acquisition tasks.
Is the UPD78F0884AGAA2-GAM-G pin-compatible with other members of the 78K0/Fx2 family?
Yes, the UPD78F0884AGAA2-GAM-G uses the LQFP-100 package and shares identical pin configuration with other 78K0/FC2 variants including UPD78F0881A–UPD78F0886A and UPD78F0894A–UPD78F0895A (A and A2 grades). This allows direct substitution within the same package footprint for memory or peripheral scaling without PCB redesign.
