Holtek HT48R0xB/N, HT46R0xB/N New Small Package MCU Series

01/13/2010

Holtek is pleased to announce the release of its new small package MCU devices, the I/O type HT48R0xx and the A/D type HT46R0xx series. The ultra small 10-pin MSOP package types have part numbers HT48R01B/02B for the I/O type and HT46R01B/02B for the A/D type. The 16-pin NSOP package types have part numbers HT48R01N/02N for the I/O type and HT46R01N/02N for the A/D type. With a footprint outline of only 3mm x 3mm, the 10-pin MSOP package types are even smaller than 8-pin DIP/SOP making them especially suitable for applications where space is at a premium.

In the area of functionality, this new series includes an OTP Program Memory capacity ranging from 1Kx15 to 2Kx15, 96 bytes of SRAM Data Memory, 8 to 10 I/O pins, an internal Time Base and two 8-bit timers. The A/D type devices include a 12-bit internal high speed ADC and an 8-bit PWM output. Four types of system oscillators are provided, a high frequency crystal type, low frequency crystal (32KHz) type, an external RC oscillator and internal RC oscillator. The internal RC oscillator can be chosen to have one of three different frequencies, 4MHz, 8MHz or 12MHz, each with a tolerance of ±2%.

This new small package MCU series, with their special characteristics of flexible I/O functions, low cost and small outlines will find widespread use in a huge range of application areas.

To support these devices, Holtek provides a full suite of hardware and software development tools, known as the HT-IDE3000. These tools include a hardware In-Circuit Emulator as well as functions such as trace analysis, programmable breakpoint setting and many others to ensure that designers have their new product designs debugged and up and running in the shortest time possible.
