描述 Description

As Telink’s unique Electro-Magnetic (EM) touch controller IC, the TLSC3590 integrates a powerful 32-bit MCU, a 64KB OTP, 16KB SRAM, an antenna controller, up to 5 channels of PWM, a 12-bit ADC, four timers, a SYNC module, abundant I/O interfaces, and nearly all of the peripheral blocks needed.

The TLSC3590 is designed to work with PCB type antenna and ITO type antenna and offers excellent accuracy and linearity. The latter type of sensors can be easily combined with multi-touch capacitive controller to support dual sense touch applications where both finger and pen inputs are possible. Featured with active/passive pen support, the TLSC3590 also has digital modulation signal reception capability for advanced digital pen support.
