Frequently Asked Questions
What display capability does PIC16F1933-I/SO integrate, and how many LCD segments can it drive directly?
PIC16F1933-I/SO includes an on-chip LCD driver that can directly drive segmented LCD panels without an external controller. The driver supports up to 4 commons and 8 segments, enabling control of 32 LCD segments total, which is sufficient for numeric displays on appliances, utility meters, and consumer electronics panels.
At what minimum supply voltage can PIC16F1933-I/SO operate, and what clock speed is achievable at that voltage?
PIC16F1933-I/SO can operate from a minimum supply voltage of 1.8 V while running at up to 16 MHz, making it suitable for 2-cell alkaline or single-cell Li-ion battery-powered products. The full 20 MHz maximum clock speed is available at higher supply voltages, allowing designers to balance performance and power consumption based on available battery rail.
How much non-volatile storage does PIC16F1933-I/SO provide, and in which applications is that EEPROM capacity most useful?
PIC16F1933-I/SO provides 7 KB of Flash program memory and 256 bytes of on-chip EEPROM for data storage. The 256-byte EEPROM is well matched to storing calibration constants, user configuration settings, and event counters in appliances, meters, and industrial controllers, where parameters must survive power cycles without external memory devices adding cost and board space.
