PIC16LC926T-I/L Обзор
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, peripherals, and I/O into one device. The PIC16LC926 belongs to the mid-range PIC family, sitting in the 8-bit MCU segment of the broader embedded semiconductor hierarchy: microcontroller -> embedded processor -> semiconductor device. Within Microchip's portfolio it is part of the LCD-driver equipped PIC16LC9xx line designed for human-machine interface (HMI) applications such as metering, instrumentation, white goods, and consumer appliances.
Key features include an on-chip LCD driver with up to 192 segment support, a 10-bit successive-approximation Analog-to-Digital Converter (ADC), a USART for asynchronous serial communication, two 8-bit timers and one 16-bit timer, an SSP module for SPI and I2C, and a brown-out detect / power-on reset block. The device uses a 14-bit instruction word and a Harvard architecture with separate program and data buses, allowing single-cycle instruction execution except for program branches.
Typical applications include electronic utility meters with multi-digit LCD readouts, medical devices such as blood-pressure monitors and glucose meters, point-of-sale terminals, white-goods control panels, industrial process displays, and any battery- or line-powered HMI requiring integrated segment-LCD driving without an external driver IC.
When designing with this part, allocate the PLCC land pattern (JEDEC MO-047) carefully because the through-hole PLCC socket allows easy prototyping but requires a different footprint than the TQFP variant. Plan I/O pin assignments early, since the LCD segment pins are multiplexed with digital I/O and cannot be reassigned arbitrarily.

Типичное применение
PIC16LC926T-I/L подходит для 6 применениеs: Electronic Utility Meters, Medical Monitoring Devices, White Goods Control Panels, Point-of-Sale Terminals, Industrial Process Displays, Consumer Appliances with LCD Readout.
Electronic Utility Meters
The PIC16LC926T-I/L fits electronic utility meters because its integrated LCD driver supports up to 192 segments, enough to display kWh, voltage, current, and tariff readouts on a multi-digit glass LCD. The 10-bit ADC samples current shunts and voltage dividers with sufficient resolution for billing-grade accuracy, and the 14 KB OTP memory stores calibration tables, metrology firmware, and Tamper-detection logic. At 2.5-6 V low-voltage operation, the device runs directly from a battery-backed supply during power outages. Compared with discrete LCD-driver + MCU solutions, the LC926 eliminates an external driver IC, reducing BOM cost and PCB area. The industrial temperature range (-40 C to +85 C) supports outdoor meter enclosures without additional thermal management.

Medical Monitoring Devices
The PIC16LC926T-I/L is well suited for medical devices such as blood-pressure monitors, glucose meters, and digital thermometers that require a clear numeric LCD readout. The 192-segment LCD driver directly displays measurement results without an external driver, while the 10-bit ADC reads sensor inputs (pressure transducers, thermistor bridges, electrochemical strips). Low-voltage operation (2.5-6 V) suits 3 V battery-powered designs, extending battery life for portable use. The PIC16 mid-range core provides deterministic interrupt latency, important for real-time sensor sampling. Compared with higher-end 32-bit MCUs, the LC926 reduces BOM cost and simplifies FDA submission by minimizing firmware complexity. The 68-PLCC package is convenient for low-volume medical production with through-hole socket assembly.

White Goods Control Panels
The PIC16LC926T-I/L serves white-goods control panels (washing machines, dishwashers, ovens) where a multi-segment LCD shows cycle status, temperature, and timer. The on-chip LCD driver eliminates the need for a separate HT1621 or similar driver, reducing BOM cost and improving ESD immunity by removing a long PCB trace to the LCD. The integrated USART and SSP peripherals interface to motor-control and sensor front-ends, while the 10-bit ADC reads temperature probes and water-level sensors. Industrial temperature range (-40 C to +85 C) handles under-cabinet oven and freezer environments. Compared with character-LCD + external MCU architectures, the LC926 solution saves both PCB area and assembly cost.

Point-of-Sale Terminals
The PIC16LC926T-I/L supports compact point-of-sale (POS) terminals and handheld readers with its integrated LCD driver for transaction amount, battery, and status display. The 14 KB OTP program memory fits lightweight payment firmware, and the USART connects to a magnetic-stripe or smart-card front-end. The 10-bit ADC monitors battery voltage and charger current, important for battery-powered POS terminals. The low-voltage 2.5-6 V operating range simplifies power-path design when sharing a Li-ion cell. Compared with character LCD + 8-bit MCU combinations, the LC926's segment LCD driver produces cleaner custom icons and reduces external component count.
Рекомендуется
Industrial Process Displays
The PIC16LC926T-I/L fits industrial process displays where multi-digit or alphanumeric readouts show temperature, pressure, flow rate, and setpoints. The integrated 192-segment LCD driver supports up to 8 multiplexed commons, sufficient for 16-character alpha-numeric or 8-character multi-digit displays. The 10-bit ADC accepts 4-20 mA loop inputs through a sense resistor, and the USART connects to PLC or SCADA networks. Industrial temperature range (-40 C to +85 C) handles factory-floor conditions. Compared with PLC HMI modules, the LC926-based display is a cost-effective solution for distributed sensor readouts that don't require full color graphics.

Consumer Appliances with LCD Readout
The PIC16LC926T-I/L is ideal for consumer appliances such as coffee machines, microwave ovens, air conditioners, and home automation panels with a multi-segment LCD for status display. The integrated LCD driver removes the need for a separate HT1621 or PCF8576 LCD driver, reducing BOM cost and PCB complexity. The 2.5-6 V low-voltage operation suits 3.3 V or 5 V designs powered by AC/DC adapters or USB. The PIC16 mid-range core runs at up to 20 MHz, enough for control-loop timing and UI refresh. Compared with character-LCD + 8-bit MCU designs, the LC926 enables slimmer form factors and lower assembly cost for mass-produced consumer products.

Заметки по проектированию
The 68-pin PLCC footprint follows JEDEC MO-047, with 1.27 mm pitch pads arranged in a square 24.23 x 24.23 mm land pattern. For prototype-friendly designs, use a through-hole PLCC socket so the OTP part can be replaced without rework. For SMT-only assemblies, the PLCC can be directly soldered, but rework is harder than TQFP. Ensure the land pattern includes a center thermal relief if the application uses high I/O drive strength, although most PIC16LC926 designs do not require this.
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, plus a 10 uF bulk capacitor on the main supply rail. The PIC16LC926 has multiple VDD/VSS pins that must all be connected. Brown-out detect (BOD) should be enabled in configuration fuses to ensure clean startup at low battery voltages (below 2.5 V the OTP read becomes unreliable). For battery-powered metering, design the MCLR pull-up with a 10 kohm resistor and 100 nF capacitor for a clean power-on-reset.
OTP memory can be programmed only once. Plan firmware development on a Flash-based sibling (PIC16F926-I/L) before committing to LC926 for production. The LCD segment pins are multiplexed with digital I/O; if your design uses both functions, verify that the LCD driver does not conflict with digital I/O timing. Finally, note that the LC926 family has reached maturity - second-source or pin-compatible replacements are limited, so design with future availability in mind.
