Key Features
- 8-bit PIC12 core up to 20 MHz with 1.8 V minimum supply at 16 MHz, enabling direct operation from a single lithium coin cell throughout its discharge curve
- 3.5 KB Flash and 256 bytes of RAM in an 8-pin SOIC-8 footprint, delivering MCU functionality in the smallest practical through-hole-replaceable SMT package
- Integrated multi-channel ADC for analog signal acquisition, eliminating external ADC ICs in simple sensor interface and signal-conditioning designs
- Extended temperature range (-40°C to +125°C) supporting industrial and automotive-adjacent applications in harsh environments with the PIC12LF low-power family
Applications
The PIC12LF1552-E/SN is ideal for ultra-compact, low-power applications including capacitive touch sensor controllers, HVAC duct sensors, and battery-powered wireless modules where PCB area and pin count are tightly constrained. Its 1.8 V minimum supply and low-power sleep modes allow coin-cell or AAA-battery operation for years in infrequently sampled environmental monitors. The 8-pin SOIC package fits on less than 20 mm2 of PCB, making it suitable for miniaturized consumer electronics, toy accessories, and wearable end nodes.

Frequently Asked Questions
At what clock frequency can PIC12LF1552-E/SN run at 1.8 V, and why does that matter for single-cell coin-battery designs?
The PIC12LF1552-E/SN runs at up to 16 MHz when supplied at 1.8 V minimum, and can reach 20 MHz at higher voltages. This means a CR2032 coin cell at end-of-discharge near 2.0 V still provides enough headroom for 16 MHz operation, avoiding the need for a boost regulator and extending battery life in passive environmental sensors.
How does PIC12LF1552-E/SN's 8-pin SOIC package compare to an 8-pin DIP for a PCB redesign targeting SMT assembly?
The SOIC-8 package occupies approximately 19 mm2 of PCB area versus 68 mm2 for a DIP-8, a 72% reduction in footprint; it is also compatible with standard SMT pick-and-place reflow processes running at 260°C peak temperature, eliminating manual insertion and hand-soldering steps in medium-to-high volume production lines.
Is PIC12LF1552-E/SN suitable for reading NTC thermistor signals directly, without an external ADC?
Yes. The integrated multi-channel ADC samples the thermistor voltage divider directly at the MCU pin with sufficient resolution for typical -40°C to 125°C NTC linearization, and the 20 MHz core completes a 10-bit conversion plus Steinhart-Hart lookup in under 5 µs, making external ADC ICs unnecessary for single-channel temperature sensing applications.
How does PIC12LF1552-E/SN handle extended industrial temperature conditions?
The E-suffix grade of PIC12LF1552-E/SN is rated from -40°C to +125°C, covering both cold outdoor installations at -40°C and hot industrial enclosures or engine-compartment locations where ambient can exceed 100°C, making it reliable in motor-overtemp sensors, duct temperature monitors, and under-hood automotive accessories without additional derating.
