What are the key features of PIC12C509A-04I/P?

8-bit PIC12 OTP core running at up to 4 MHz with 1K x 12-bit program memory and 41-byte data RAM
6 general-purpose I/O pins with individually selectable direction for compact control tasks in 8-pin DIP package
Internal 4 MHz RC oscillator option eliminates external crystal, reducing BOM cost for simple consumer applications

What is PIC12C509A-04I/P used for?

The PIC12C509A-04I/P is suited for simple consumer products requiring low-cost one-time programmable (OTP) control logic, such as remote controls, appliance timers, and toy controllers. Its 8-pin DIP package and internal oscillator minimize external component count, enabling minimal BOM cost designs. The ultra-low power sleep mode supports battery-powered applications requiring infrequent processing at 4 MHz.

Frequently Asked Questions

What are the program memory size and maximum clock speed of the PIC12C509A-04I/P?

The PIC12C509A-04I/P has 1024 x 12-bit words of OTP program memory and runs at a maximum clock frequency of 4 MHz. With 41 bytes of data RAM, this device is well suited for simple sequencing and state-machine applications in cost-sensitive consumer products.

How many I/O pins does the PIC12C509A-04I/P provide and what voltage range does it support?

The PIC12C509A-04I/P provides 6 general-purpose I/O pins in the 8-pin DIP package and operates from a supply voltage of 2.5V to 5.5V. This wide voltage range makes it suitable for both 3V coin-cell battery applications and standard 5V systems.

Is PIC12C509A-04I/P a suitable lower-cost replacement for flash-based MCUs in high-volume simpler products?

Yes, the PIC12C509A-04I/P OTP version is a cost-effective alternative to flash-based PIC12F devices in high-volume production where code is finalized. OTP parts are typically lower cost per unit than flash variants. However, since OTP cannot be reprogrammed, the PIC12C509A-04I/P is only appropriate when firmware is stable and final before programming.
