PIC14000T-20/SS - 8-Bit 20MHz 7KB OTP MCU | Microchip
MPN: PIC14000T-20/SS ✓ Hoạt độngPIC14000T-20/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, data RAM, and integrated peripherals such as timers, A/D converters, and communication interfaces. The PIC14 family sits between the baseline PIC10/12 series and the mid-range PIC16 family, offering a RISC instruction set, deterministic execution timing, and OTP or flash program memory for embedded control. Microcontrollers serve as the decision-making core of virtually every embedded product, replacing discrete logic with software-defined behavior.
Key features of the PIC14000T-20/SS include the 8-bit PIC RISC core, 7KB OTP program memory suitable for production-volume firmware, 192 bytes of data RAM for variable storage, a 20MHz clock providing 5 MIPS throughput, and an industrial-grade operating temperature range suitable for commercial embedded designs. The SSOP-28 package (5.30mm body width) provides a compact surface-mount footprint compatible with standard 0.65mm-pitch land patterns.
From a technical depth perspective, the PIC14000 integrates mixed-signal peripherals including A/D conversion channels and analog comparators alongside the digital core, making it suitable for sensor-interface and control applications. The OTP memory allows one-time programming during manufacturing, offering lower per-unit cost than flash for high-volume production runs.
Typical applications include industrial automation controllers, sensor signal conditioning, consumer electronics interfaces, motor control sub-systems, and mixed-signal embedded products. Its combination of analog and digital peripherals on one die simplifies BOM for cost-sensitive designs.
When designing with the PIC14000T-20/SS, ensure the development toolchain matches the OTP variant (PIC14000 OTP parts require a compatible programmer; firmware must be finalized before programming). Decoupling capacitors of 0.1uF should be placed close to VDD/VSS pairs to maintain analog performance.

Ghi chú thiết kế
The PIC14000T-20/SS operates from a 5V typical supply with 6V absolute maximum. Place a 0.1uF decoupling ceramic capacitor close to each VDD/VSS pair (pins 9/10 and 19/20) to suppress digital switching noise. For mixed-signal accuracy, add a 10uF bulk capacitor near the analog supply rail and consider a ferrite bead between digital and analog VDD traces.
The 28-SSOP package has 0.65mm pitch - design the PCB land pattern per IPC-7351 nominal-density standards. Use solder mask-defined (SMD) pads rather than non-solder mask-defined (NSMD) for production reliability. Maintain at least 0.2mm clearance between copper traces and package leads to prevent solder bridging during reflow.
Do not attempt to reprogram the PIC14000T-20/SS after the OTP memory has been written - OTP supports only a single programming cycle. Ensure firmware is fully validated on equivalent flash-based PIC16F or PIC18F prototypes before committing to OTP production. Also verify the development toolchain (MPLAB X IDE, PICkit programmer) is configured for OTP target devices.
At 20MHz clock with all peripherals active, the PIC14000T-20/SS typically dissipates under 100mW - no heatsink is required for the SSOP-28 package. However, in enclosed designs with limited airflow, ensure the ambient temperature stays within the commercial 0C to +70C range. For higher-temperature deployments, switch to the PIC14000T-20I/SS industrial variant.
Thông tin tuân thủ
RoHS and lead-free status was not confirmed in the verified distributor data; Microchip's PIC14000 family typically offers RoHS-compliant variants but specific orderable part number suffix must be verified before placing production orders. AEC-Q100 is not applicable - PIC14000T-20/SS is not an automotive-grade qualified part.
