The LT7688 is an high-performance Uart TFT panel Controller. Its internal combination of Levetop Semiconductor's 32bit MCU - LT32U02 and TFT Graphics Accelerator - LT768's core architecture. Its main function is to provide Uart serial communication, allowing the main MCU to easily show the pictures on TFT panel through simple instructions. The LT7688 supports The TFT display resolution can be from 320 x 240 (QVGA) to 1280 x 1024 (SXGA), supporting the RGB interface of 16/18bits.
LT768x are a series of high-performance LCD graphics acceleration display controller introduced by LeveTop after 32-bit MCU and capacitive touch controller. The resolution displayed can be supported by 320*240 (QVGA) to 1280*1024 (SXGA). The display supports the RGB interface of 16/18/24-bits. Its powerful display function is very suitable for use in electronic products with TFT LCD screen, such as home appliances, multi-function machines, industrial equipment, industrial control, electronic instruments, medical equipment, man-machine interface, testing equipment and other products.


LT32A01 and LT32U02 are two high performance, low cost 32-bit MCU. Among them, LT32U02 has the highest 72MHz operating frequency, 64KB Flash, 8KB SRAM memory, USB 2.0, Comparators. LT32A01 has the highest 48MHz operating frequency, 32KB Flash, 4KB SRAM. Each of the two offers a variety of standard communication interfaces, including SPI, I2C, SCI (UART), PWM, Analog input (12-bit ADC), interrupt input, and many GPIO interfaces.
LT5926 and LT5928 are two low-cost, low-power blue tooth controller which integrated by 32bit MCU - LT32A01 or LT32U02 with 2.4GHz Bluetooth wireless transceiver. The bluetooth was integrated with transmitter, receiver, frequency synthesizer and GFSK modem. The power of transmitter is adjustable. The peripheral circuit is simple and only a few passive devices are needed. The maximum transmission power is up to -28 ~ +4dBm, when transmitting GFSK signal, and the receiving sensitivity is up to -85dBm.


LT2305 is a 60 channels analog front end capacitor multi-touch screen control chip. It adopts LeveTop's patented touch sensing technology -TPWS( Touch prediction and window sampling) , which has 4 parallel capacitors to digital converters, allowing SPI interface to conduct capacitance measurement on 500KHz operation. The chip adopts programmable sensing architecture and extensible serial bus interface.
LT6101 is a self capacitive touch key controller with extremely low consumption. It adopts LeveTop's patented capacitive touch key information detection technology, which can achieve very low dynamic power consumption and high precision of touch signal detection. Meanwhile, it can be used to replace mechanical keys, reduce contact loss, and optimize the appearance and texture of the product. LT6101 can not only work as a slave of external controller, but also as a independent mainframe.
