MCP19114/5
This document includes the programming
specifications for the following devices:
• MCP19114
• MCP19115
1.0 PROGRAMMING THE
MCP19114 AND MCP19115
DEVICES
The MCP19114/5 devices are programmed using a serial
method. The Serial mode will allow these devices to be
programmed while in the user’s system. These
programming specifications apply to all of the above
devices in all packages.
1.1 Hardware Requirements
This family of devices requires one power supply for
VIN, see Table 6-1. The VDD that is used to bias all
internal circuitry is internally generated and regulated
to 5V. Analog circuitry is powered from internally
generated AVDD and is regulated to 4V.
1.2 Program/Verify Mode
The Program/Verify mode for this family of devices
allows programming the user program memory, the
user ID locations, the Calibration Word and the
Configuration Word.
