 HT68FB40
HT68FB30/HT68FB40/HT68FB50/HT68FB60
General Description
The HT68FBx0 series of devices are Flash Memory I/O
type 8-bit high performance RISC architecture
microcontrollers with a USB interface. Offering users
the convenience of Flash Memory multi-programming
features, these devices also include a wide range of
functions and features. Other memory includes an area
of RAM Data Memory as well as an area of EEPROM
memory for storage of non-volatile data such as serial
numbers, calibration data etc.
Analog feature includes dual comparator functions. Mul-
tiple and extremely flexible Timer Modules provide tim-
ing, pulse generation and PWM generation functions.
Communication with the outside world is catered for by
including fully integrated SPI or I2C interface functions,
two popular interfaces which provide designers with a
means of easy communication with external peripheral
hardware. Protective features such as an internal
Watchdog Timer, Low Voltage Reset and Low Voltage
Detector coupled with excellent noise immunity and
ESD protection ensure that reliable operation is main-
tained in hostile electrical environments.
A full choice of HXT, LXT, ERC, HIRC and LIRC oscilla-
tor functions are provided including a fully integrated
system oscillator which requires no external compo-
nents for its 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 minimize power
consumption.
The device contains a single USB Full-speed interface
to allow data communication with an external USB host
controller. It is particularly suitable for applications which
require data communication between PCs and periph-
eral USB hardware.
An extensive choice of oscillator functions is provided
including a fully integrated system oscillator which re-
quires no external components for its 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 opera-
tion and minimise power consumption. The devices also
include flexible I/O programming features, Time-Base
functions and a range of other features.
Selection Guide
Most features are common to all devices, the main feature distinguishing them are Memory capacity, I/O counts, TM
features, stack capacity and package types. The following table summarises the main features of each device.
