The HT82B40R from Holtek is a high-performance, 8-bit RISC architecture microcontroller designed for multiple I/O control applications. It features an integrated USB 2.0 low-speed interface with support for up to 3 endpoints. The device operates within a voltage range of 3.3V to 5.5V and includes a fully integrated 6MHz or 12MHz oscillator.
Key electrical specifications include 4096 bytes of program memory and 160 bytes of data RAM. It supports up to 34 bidirectional I/O lines, each with wake-up functions. The microcontroller is equipped with an 8-bit and a 16-bit programmable timer/event counter, a watchdog timer, and power-down/wake-up features to reduce power consumption. Instruction cycle time is up to 0.33µs at 12MHz system clock and 5V VDD.
Available in 28/48-pin SSOP, 32-pin QFN, and 48-pin LQFP packages, the HT82B40R is suitable for computer peripheral applications, industrial control, and consumer products. It also includes an integrated 1.5kΩ resistor for USB applications.
