PICmicro MID-RANGE MCU FAMILY

Introduction
All midrange devices can be In-Circuit Serial Programmed (ICSP™) while in the end application
circuit. This is simply done with two lines for clock and data, and three other lines for power,
ground, and the programming voltage.
In-Circuit Serial Programming (ICSP™) is a great way to reduce your inventory overhead and
time-to-market for your product. By assembling your product with a blank Microchip microcontrol-
ler (MCU), you can stock one design. When an order has been placed, these units can be pro-
grammed with the latest revision of firmware, tested, and shipped in a very short time. This
method also reduces scrapped inventory due to old firmware revisions. This type of manufactur-
ing system can also facilitate quick turnarounds on custom orders for your product.
Most people would think to use ICSP with PICmicro™ OTP MCUs only on an assembly line
where the device is programmed once. However, there is a method by which an OTP device can
be programmed several times depending on the size of the firmware. This method, explained
later, provides a way to field upgrade your firmware in a way similar to EEPROM- or Flash-based
devices.
