What are the key features of PIC16LC54C-04/SS?
- 8-bit PIC core with 768 bytes OTP program memory and 4 MHz clock for cost-sensitive embedded control tasks
- Low-voltage operation from 2.5 V enabling battery-powered and energy-harvesting designs
- 20-pin SSOP (R-PDSO-G20) package enables compact PCB integration with 12 general-purpose I/O pins
What is PIC16LC54C-04/SS used for?
The PIC16LC54C-04/SS targets cost-sensitive, low-power embedded control applications such as home appliance timers, toy electronics, and simple keypad interfaces where 8-bit processing at up to 4 MHz is sufficient. Its OTP program memory and 20-pin SSOP package allow one-time field programming in small production runs without the cost of flash-based devices. It is also used in low-cost remote controls and sensor readout modules running from coin-cell or AA battery power supplies.

Frequently Asked Questions
What program memory size and clock frequency does PIC16LC54C-04/SS offer?
The PIC16LC54C-04/SS provides 768 bytes of OTP (one-time programmable) program memory and a maximum clock frequency of 4 MHz. These specifications are well-matched to simple control tasks such as LED sequencing, switch debouncing, or sensor polling in battery-powered consumer devices, where code size is small and real-time demands are modest.
What supply voltage range allows PIC16LC54C-04/SS to operate in low-power battery applications?
The PIC16LC54C-04/SS is specified for low-voltage operation starting from approximately 2.5 V, making it compatible with single-cell Li-ion batteries and two-cell alkaline packs. This low supply floor extends usable battery life in portable gadgets and wireless sensor nodes where supply voltage sags toward end-of-discharge.
How does PIC16LC54C-04/SS fit into a cost-sensitive production run compared to a flash-based PIC?
In very-high-volume applications where firmware is finalized before production, the OTP architecture of PIC16LC54C-04/SS eliminates the per-unit cost premium of embedded flash, reducing silicon cost by roughly 10% to 30% versus equivalent flash PIC devices in the same 8-bit, 20-pin SSOP family. However, OTP devices cannot be reprogrammed after initial write, so they are suitable only when the 768-byte firmware image is fully validated before programming.
