UPD78F9116AC-A

Product Overview

The UPD78F9116AC-A from Renesas Electronics Corporation is an 8-bit microcontroller built around a 78K0S core. It provides 16KB (16K x 8) of FLASH program memory, 256 x 8 RAM, and 20 I/O pins. The device supports a 1.8V to 5.5V supply range and includes a 40x10b A/D converter. Serial connectivity is provided through UART/USART and 3-wire SIO interfaces. It uses through-hole mounting and is specified for an operating temperature range of -40°C to 85°C (TA).

Key Features

• 8-bit 78K0S core with 16KB (16K x 8) FLASH program memory
• 256 x 8 RAM and 20 I/O pins
• 40x10b A/D converter
• UART/USART and 3-wire SIO serial interfaces
• 1.8V to 5.5V supply voltage range
• Through-hole mounting and -40°C to 85°C (TA) operating temperature range

Applications

• Embedded control systems requiring an 8-bit microcontroller with FLASH program memory
• Analog measurement systems using the 40x10b A/D converter
• Serial communication devices that use UART/USART or 3-wire SIO interfaces
• Embedded designs operating from a 1.8V to 5.5V supply range

Design & Procurement Notes

When specifying the UPD78F9116AC-A, confirm that the 16KB (16K x 8) FLASH program memory and 256 x 8 RAM are sufficient for the firmware and runtime data. The 20 I/O count and 40x10b A/D converter should be checked against sensor and control pin requirements, and the UART/USART plus 3-wire SIO connectivity should be matched to the intended serial protocol. The 1.8V to 5.5V supply range and -40°C to 85°C (TA) operating temperature range are important for power and environmental design, while the through-hole mounting style affects PCB layout and assembly method.
