TM1620

The TM1620 is a versatile LED driver IC designed to control up to 8 segments × 16 digits or 128 individual LEDs. It features a serial interface (SPI-like) for communication with microcontrollers, reducing pin usage. Key functions include:
- Multiplexing support (1/8 duty cycle)
- Built-in display RAM for storing segment data
- Adjustable brightness (8 levels via PWM)
- Low power consumption
Commonly used in appliance displays, industrial panels, and consumer electronics, the TM1620 simplifies LED matrix or 7-segment control. It operates at 3V–5.5V, making it compatible with most MCUs.
Advantages:
✔ Fewer I/O pins required
✔ On-chip memory reduces MCU workload
✔ Supports multiple display formats
For basic use, send commands (e.g., display mode, address) followed by segment data via DIN, CLK, and STB pins.

The TM1620 is a memory mapping LED driver with key scanning capabilities. Key features:
- LED Drive: Supports 8 segments × 16 digits (128 segments total) or 7 segments × 14 digits with 14×4 matrix key scanning.
- Communication: Serial interface (CLK, STB, DIO) for easy MCU interfacing.
- Brightness Control: 8-level adjustable PWM dimming.
- Key Scan: Built-in 14×4 matrix key scanning with internal pull-down resistors.
- Low Power: Supports 3V–5.5V supply, suitable for battery-powered devices.
- Memory Mapping: Includes display RAM for storing segment data.
