HT66F2390-48LQFP
Description
The HT66F2390 is an 8-bit MCU with Holtek’s high-performance RISC architecture core. It is a member of Holtek Advanced A/D Flash MCU family. The device has achieved IEC/UL 60730 certification, they are supplied with a software library dedicated for IEC/UL 60730 verification to assist users in their product development and verification. The device includes an integrated hardware CRC engine for flash program memory self-diagnostic testing, allowing developers to reduce test times and also reduce the loading on MCU resources. The device also includes a large LED current drive capability, which permits LEDs to be driven without requiring external current-limiting resistors or transistors.
