TM1640 Description

Short technical summary and product information.

The TM1640 is an LED (Light Emitting Diode Display) drive control circuit integrating MCU digital interface, digital latch, and LED high voltage drive circuit. It is manufactured using PowerCMOS technique and operates with a logic power voltage range of -0.5 to 7.0 V, typically 5V.

 

Key features include an 8-section by 16-bit display mode supporting common cathode digital tube output, an adjustable brightness circuit with 8 duty cycle levels, and a dual-line serial interface (CLK, DIN). The device has a built-in RC oscillator operating at 450 KHz ±5%, a power-on reset circuit, and an auto-blanking circuit.

 

Available in SOP28 and SSOP28 packages, the TM1640 is suitable for applications requiring display drive in electronic scales and other small home appliances. It operates within a temperature range of -40 to +85 °C.
