MCU Products
Professional microcontroller solutions for your applications
Overview
The devices are OTP type 8-bit high performance RISC architecture microcontrollers, which are designed for various voice application terminal products such as smart home appliances, consumer electronic products, etc.
For memory features, the memory also includes an area of RAM Data Memory as well as an area of up to 32Mbit Voice Flash Memory.
A single extremely flexible Timer/Event Counter provides timing, event counting and pulse wide measurement functions. In addition, an internal LDO function provides power to the Voice Flash Memory. Communication with the outside world is catered for by including fully integrated SPI and I²C interface functions, these popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
A full choice of internal high and low speed oscillators are provided, the two fully integrated system oscillators require no external components for their implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimise power consumption.
The devices integrate a Delta Sigma PWM driver, for which the devices have a digital programmable volume control with a wide range. The devices also support the Peripheral IC mode, implementing voice editing together with Holtek Voice Workshop. The inclusion of flexible I/O programming features, Time Base functions, along with many other features ensure that the devices will find excellent use for voice application terminal products.

e-Socket
(Programming Hardware)The e-Socket is a socket which is used together with e-WriterPro. MCUs with the same package types can use the same e-Socket for programming. It is not necessary to purchase individual programming adaptors for different MCUs. The e-Socket is designed with a programming counter which enables the e-WriterPro to remind users when to replace the e-Socket with a new one after a certain amount of times. This function is provided to maintain high programming quality.
e-WriterPro2
(Programming Hardware)The e-WriterPro2 is an upgraded version programmer of the e-WriterPro, which is fully compatible with the previous version, and it can be used not only as a programming tool for all of Holtek’s OTP and Flash devices during development stage but can also be used for small to medium volume production purposes.

GangWriter00-8
(Programming Hardware)The product is an upgraded gang programmer of Gang-Writer32-8 and Gang-Writer8-8. It is composed of a development board and two programming modules and supports programming both Holtek 8-bit and 32-bit MCUs. Each programming module includes 4 programming interfaces, and one development board can connect up to 4 programming modules. This allows the product to program up to 16 MCUs simultaneously, with support for parallel programming across 2, 4, 6, 8, 12, and 16 sites.
