Frequently Asked Questions
What is the maximum clock frequency and program memory size of the PIC12LC509A-04I/SN?
The PIC12LC509A-04I/SN runs at up to 4 MHz and includes 1K words of one-time programmable (OTP) flash. The 8-bit PIC12 core handles basic control loops efficiently within this memory budget, making it cost-effective for simple dedicated-function firmware.
How many I/O pins does the PIC12LC509A-04I/SN provide, and is it suitable for battery-powered products?
The device provides 6 bidirectional I/O pins in its SOIC-8 package, supporting direct interfacing to LEDs, sensors, and small actuators. Its low operating current and wide supply range make it well suited for 3 V or 5 V battery-powered consumer or industrial products.
When should a designer choose OTP memory over Flash for a microcontroller like the PIC12LC509A-04I/SN?
OTP memory is preferred in high-volume production where firmware is locked at manufacture, reducing per-unit cost versus reprogrammable Flash devices. The PIC12LC509A stores up to 1K words permanently, eliminating read-back risk in security-sensitive applications such as anti-tamper circuits or calibration-embedded sensors.
What is the lifecycle status of the PIC12LC509A-04I/SN, and how should procurement teams plan for long-term supply?
Introduced in 1996, the PIC12LC509A family has a YTEOL (years to end-of-life) indicator of approximately 3 years, signalling it is approaching end-of-life. Buyers sourcing for long-lifecycle industrial or appliance designs should evaluate migration to active Microchip PIC12F or PIC16F devices with equivalent 8-bit cores and compatible pinouts to secure ongoing supply.
