HT82A623R/HT82A6208/HT82A6216 -- A/D Type Full Speed USB 8-Bit MCU with SPI
General Description
The HT82A623R, HT82A6208 and HT82A6216 are 8-bit high performance RISC-like microcontrollers designed for USB keyboard, mouse and joystick product applications. The devices are also suitable for use in home appliances, particularly for use in high-level household appliances such as microwave ovens, washing machines and air conditioner products.
The HT82A6208 and HT82A6216 devices also possess an internal 8M or 16M Flash Memory further enhancing and expanding their application possibilities.
The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, USB Interface, Watchdog timer, SPI interfaces, Power Down and wake-up functions, enhance the versatility of these devices to suit a wide range of application possibilities.
The HT82A6208 contains a 8,388,608 bit serial Flash memory, which is configured as 1,048,576x8 internally. The HT82A6216 contains a 16,777,216 bit serial Flash memory, which is configured as 2,097,152x8 internally. The HT82A6208/HT82A6216 feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by the CS# input.
The device provides a sequential read operation on the whole chip.
After a program/erase command is issued, auto program/erase algorithms are executed which program/erase and verify the specified page or byte/sector/block locations. A program command is executed on a page (256 bytes) basis, and an erase command is executed on a chip or sector (4K-bytes) or block (64K-bytes) basis.
To provide the user with ease of interface, a status register is included to indicate the status of the device. The status read command can be issued to detect completion status of a program or erase operation via the WIP bit.
When the HT82A6208/HT82A6216 is not operating and CS# is high, it can be put into the standby mode where it will draw less than 10uA/20uA DC current.
The HT82A6208/HT82A6216 contains proprietary memory cells, which reliably store memory contents even after 100,000 program and erase cycles.
