Notes:

1. This integrated circuit is based on Microchip Technology Inc.’s PIC18F2480 device. For further device

specifications, and clarification of those given, please refer to the appropriate Microchip documentation

(available at http://www.microchip.com/).

2. This spec must be met in order to ensure that a correct power on reset occurs. It is quite easily achieved

using most common types of supplies, but may be violated if one uses a slowly varying supply voltage, as

may be obtained through direct connection to solar cells or some charge pump circuits.

3. Device only. Does not include any load currents.

ELM328DSB

All values are for operation at 25°C and a 5V supply, unless otherwise noted. The ELM328 is electrically identical to the

ELM327 in all respects. For further information, refer to the ELM327 data sheet, and to note 1 below.
