Product specification

8-bit microcontroller with 4.5 kbytes OTP

memory and 32 kHz real-time clock

PCD3745A

16 LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134); see notes 1 and 2.

Notes

1. Stresses above those listed under Limiting Values may cause permanent damage to the device.

2. Parameters are valid over the operating temperature range unless otherwise specified. All voltages are with respect

17 HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take

normal precautions appropriate to handling MOS devices (see

“Handling MOS devices”).
