• Manufacturer Part Number: HD6417034B
• Description: 32-Bit RISC Microcomputer
• Manufacturer: RENESAS [Renesas Technology Corp]

14.1
The SuperH microcomputer includes an analog-to-digital converter module which can be
programmed for input of analog signals up to eight channels. A/D conversion is performed by the
successive approximations method with 10-bit resolution.
14.1.1
10-bit resolution
Eight analog input channels
User definable analog conversion voltage range
The analog conversion voltage range can be set with the analog reference power pin (AVref)
as the analog reference voltage
Rapid conversion time: 6.7 µs per channel (at 20 MHz)
Single mode or scan mode (selectable)
Four 16-bit data registers: A/D conversion results are transferred to and stored in the data
registers corresponding to channels
Sample-and-hold circuit
External trigger input can start A/D conversion
ADI: A/D interrupt request
Single mode: One-channel A/D conversion
Scan mode: A/D conversion repeated on one to four channels
Can be generated at end of each conversion cycle
Can start direct memory access controller (DMAC)
