PIC16F1705T-I/ST - 14KB Flash 8-bit MCU, 32MHz, 14-TSSOP

The Microchip Technology PIC16F1705T-I/ST is a cost-effective 8-bit Intelligent Analog flash microcontroller from the PIC® XLP™ 16F family, integrating 14KB (8K x 14) of self-programmable flash program memory and 1024 bytes of SRAM in a 14-pin TSSOP (ST) package. It operates at speeds up to 32MHz, delivers 10-bit ADC resolution, and includes on-chip op amps, an 8-bit DAC, Zero-Cross Detect, complementary output generator (COG), configurable logic cells (CLC), and Peripheral Pin Select (PPS) for maximum design flexibility. The wide 1.8V to 5.5V supply range plus eXtreme Low Power (XLP) sleep currents below 50 nA typical make it ideal for battery-powered and energy-harvesting applications. The PIC16F1705 belongs to the 8-bit microcontroller class, the broadest tier of the PIC microcontrollers family which sit above general-purpose MCUs in the embedded computing hierarchy. Unlike 16-bit dsPIC or 32-bit ARM Cortex devices, 8-bit PIC MCUs trade raw throughput for code density, deterministic interrupts, and ultra-low sleep current - qualities that continue to dominate low-cost sensor node, appliance, and consumer designs. The PIC16F1705 carries that philosophy one step further with on-chip analog peripherals (op amps, DAC, ZCD, COG, CLC) that historically required external components, reducing BOM and PCB area. Key differentiating features include two internal op amps (configurable for PGA/trans-impedance/buffer), a 10-bit ADC with computation, an 8-bit DAC, and the eXtreme Low Power (XLP) technology that allows deep sleep currents below 50 nA while retaining RAM and peripheral state. The device also provides enhanced mid-range core instruction set with hardware multiply, 49 instructions, and 16-level hardware stack. CLC, COG, and PPS are the 'core independent peripherals' that let timers, PWMs, and analog blocks interact without CPU involvement, freeing the core for power management or higher-level control. Typical applications span IoT sensor nodes, white goods and appliance control, LED lighting with analog dimming, battery chargers and fuel gauges, low-cost motor control loops using COG + op amp, and smoke/CO detector signal chains where ZCD and ultra-low standby current are decisive. Industrial use cases include 4-20mA loop transmitters, smart thermostats, and remote controls. Because the part shares the same Peripheral Pin Select map with the larger 20-pin PIC16F1709, code is portable up the family for future-proofing. When designing, plan for the 14-pin constraint early - PPS helps, but only one pin function can be assigned at a time. Use the CLC to offload timing-critical sequences from the core, and route analog signals on dedicated pins to avoid digital noise coupling. Decouple VDD with at least 100 nF plus 10 µF bulk, and respect the absolute-maximum VDD of 6.0V even though operating range stops at 5.5V. For low-power designs, verify that unused peripherals are explicitly disabled (PMDx registers) - the default reset state does not turn everything off. This page synthesizes distributor pricing, drop-in same-package alternatives, application companions and design notes that are not consolidated on the manufacturer datasheet page, giving procurement and firmware engineers a single reference for new designs and field replacements.

PIC16F1707-E/ML

PIC16F1707-E/ML - 8-Bit MCU, 32MHz, 3.5KB Flash | Microchip

The Microchip Technology PIC16F1707-E/ML is an 8-bit PIC® XLP™ flash microcontroller with 3.5KB (2K x 14 words) of program memory, 256 bytes of SRAM, and a 32MHz internal oscillator, housed in a 20-pin QFN (4x4 mm) package. It integrates two on-chip operational amplifiers, a 10-bit ADC with computation (ADC2), complementary output generator (COG), zero-cross detect (ZCD), and Peripheral Pin Select (PPS), providing a flexible analog and digital peripheral mix in a small footprint. An 8-bit PIC microcontroller is a Harvard-architecture CMOS device that executes a reduced instruction set (RISC) optimized for embedded control. PIC microcontrollers are widely used in consumer, industrial, and IoT applications because they pair deterministic interrupt response with low power consumption. Within Microchip's portfolio, the PIC16F1707 sits in the mid-range PIC16F1xxx family - positioned between baseline PIC10/12/16 devices and higher-end PIC18/PIC24 parts - and belongs to the XLP (eXtreme Low Power) sub-line, with idle currents in the microampere range. Key features include 3.5KB self-programmable flash, 256B SRAM, two op amps with configurable rails, a 10-bit ADC up to 28 channels, PWM, CCP, EUSART, I2C/SPI, and nanoWatt XLP sleep currents down to 20 nA typical. The integrated COG and ZCD make it well suited to motor control, TRIAC/SSR driving, and zero-cross switching applications that previously required a dedicated analog front end. The 20-pin QFN 4x4 mm footprint is among the smallest in the PIC16 line, making it attractive for space-constrained designs. Typical applications include LED lighting ballast, AC zero-cross switching, low-end BLDC/PMSM commutation assist, battery-powered sensor nodes, and consumer white-goods user-interface controllers. Design considerations include ensuring adequate ground copper under the exposed pad of the QFN for thermal dissipation and using the PPS feature to remap peripheral I/O to convenient package pins. This page synthesizes distributor pricing, drop-in QFN-20 alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers select a pin-compatible substitute or migrate firmware between family variants.

PIC16F1707-E/SO

PIC16F1707-E/SO - 8-Bit MCU, 2K Flash, 256B RAM | Microchip

The Microchip Technology PIC16F1707-E/SO is an 8-bit enhanced mid-range PIC16 microcontroller combining Intelligent Analog integration with extreme low-power (XLP) operation, housed in a 20-pin SOIC (7.50 mm body width) package. It integrates 2K Words of Flash program memory, 256 bytes of SRAM, and 10-bit analog peripherals for mixed-signal embedded designs. An 8-bit flash microcontroller is a single-chip computer that combines a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and configurable peripherals on one die. Within the broader semiconductor taxonomy, the PIC16F1707 sits in the hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> RISC flash MCU -> mixed-signal MCU. Its PIC16 enhanced mid-range core executes one instruction per two clock cycles, balancing code density with deterministic interrupt latency for real-time control loops. Key features include on-chip operational amplifiers, a 10-bit Analog-to-Digital Converter (ADC), Core Independent Peripherals such as the Configurable Logic Cell (CLC, also called COG in some marketing copy), Zero Cross Detect, and Peripheral Pin Select (PPS) that reassigns digital peripheral I/O to physical pins at runtime. The device operates across 1.8V to 5.5V supply, supports eXtreme Low Power (XLP) sleep currents in the nanoamp range, and offers up to 14 I/O pins depending on package variant. Technical depth: the PIC16F1707 uses a Harvard RISC architecture with separate program and data buses, instruction pipelining, and a hardware interrupt controller. PPS removes the rigid peripheral-to-pin mapping of legacy PIC16 parts, allowing the same firmware to route USART, SPI, or PWM to any available I/O - reducing PCB layout iterations when the original pin assignment cannot be routed. Typical applications include sensor signal conditioning using the on-chip op amps, battery-powered IoT nodes, home appliance user-interface controllers, LED lighting controllers with analog dimming, and small motor control loops. The combination of XLP sleep current and analog integration suits coin-cell powered products where the MCU must wake briefly to sample a sensor and return to deep sleep. Design consideration: when migrating from a legacy PIC16F to PIC16F1707, verify that your code is recompiled against the latest XC8 compiler, since PPS requires runtime unlock of peripheral mapping before first use. Also confirm the SOIC-20 land pattern matches your board footprint, because some prior PIC16 parts ship in narrower 0.300" SOIC bodies.
