• Manufacturer Part Number: h8s-2161b
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

This LSI includes a successive-approximation-type 10-bit A/D converter that allows up to eight
analog input channels and up to 16 digital input to be selected. A/D conversion for digital input is
effective as a comparator in multiple input testing.

10-bit resolution
Analog conversion voltage range can be specified using the reference power supply voltage
pin (AVref) as an analog reference voltage.
Conversion time: 13.4 µs per channel (at 10-MHz operation)
Two kinds of operating modes
Four data registers
Sample and hold function
Three kinds of conversion start
Interrupt request
nput channels: eight analog input channels and 16 digital input channels
Single mode: Single-channel A/D conversion
Scan mode: Continuous A/D conversion on 1 to 4 channels
Conversion results are held in a 16-bit data register for each channel
Software, 8-bit timer (TMR) conversion start trigger, or external trigger signal.
A/D conversion end interrupt (ADI) request can be generated
