HOLTEK New HT66F2372 Low Voltage 1.8V~5.5V MCU
Holtek is delighted to announce the release of new device additions to its Advanced Flash MCU range, the HT66F2372. This MCU is an extension product of the HT66F2362, providing richer system resources to facilitate users to develop higher-level products. The device provides 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 MCU Program Memory self-diagnostic testing, a function which allows developers to reduce test times as well as reducing MCU resource loading. It also includes a large LED current drive capability, a function which has four programmable drive current selections and which permit the LEDs to be driven without requiring external current-limiting resistors or transistors, a feature which results in reduced product components and cost. All these features add up to make the device suitable for home appliances and automotive products such as washing machines, air conditioners, vacuum cleaners, electric cars and exercise machines, etc.
With a comprehensive range of functions, the device contains a 32K×16 Flash Program Memory, a 3K×8 Data Memory, a 2K×8 Data EEPROM, multi-functional Timer Modules, a 12-bit A/D Converter which includes an internal reference voltage with a high accuracy of ±1%, a 16-bit hardware Multiplier and Divider, comparator, SPI/I²C interfaces and three groups of UART interfaces. As well as being utilised as a main product microcontroller, the MCU can also connect to other master ICs using their communication interfaces as part of an overall system. With their functional diversity, the device can be used in a huge range of home appliance control applications as well as automotive products to name but a few of the many application possibilities. With regards to packaging, the HT66F2372 is supplied in 28-pin SOP and 44/48-pin LQFP package types.
