Holtek is pleased to announce the release of its new Flash series MCUs, in the form of its I/O type HT68F1x series and the A/D type HT66F1x series. All devices meet with full industrial specifications (-40°C~85°C) and have high noise immunity. Together with their In-Circuit Programming capabilities, the devices permit program modifications to be easily implemented with the device still in-circuit, a feature which greatly enhances product flexibility.
The HT68F1x and HT66F1x series devices also include Holtek’s new multi-function timer modules. These new timer modules are capable of providing functions such as Timer/Counter, Capture, Compare Match Output, Single Pulse Output and PWM signal generation. All devices in the A/D type HT66F1x series also contain a 12-bit high speed ADC and internal voltage reference function.
The new Flash MCU device series includes 1~4K words of Program Memory and 64~192 bytes of SRAM Data Memory. In addition to their crystal and external RC oscillators, all devices also include fully internal RC oscillators, which require no external components and can provide fixed high frequencies of 4MHz, 8MHz, 12MHz and a low frequency of 32KHz. There are also four software COM outputs to drive low count pixel LCD panels.
