General Description
The HT82J30R/HT82J30A are 8-bit high performance,
RISC architecture microcontroller devices specifically
designed for A/D applications that interface directly to
analog signals, such as those from sensors.
The mask version HT82J30A is fully pin and functionally
compatible with the OTP version HT82J30R device.
The advantages of low power consumption, I/O flexibil-
ity, programmable frequency divider, timer functions,
oscillator options, multi-channel A/D Converter, Pulse
Width Modulation function, Watchdog timer, SPI
· 6-level subroutine nesting
· 16 channel 8-bit resolution A/D converter
· 1 channel (6+2)-bit PWM output shared with an I/O
line
· Bit manipulation instruction
· 15-bit table read instruction
· 63 powerful instructions
· LVR reset voltage of 3V±0.3V
· All instructions executed in one or two machine
cycles
· PB2, PB3, PD4, PD7 can be optioned as either
CMOS or NMOS outputs
· Integrated dual SPI interfaces
· 28-pin SKDIP/SOP and 44-pin QFP packages
interfaces, Power Down and wake-up functions, en-
hance the versatility of these devices to suit a wide
range of A/D application possibilities such as sensor
signal processing, motor driving, industrial control, con-
sumer products, subsystem controllers, etc. With the
provision of dual SPI interfaces the devices are espe-
cially suitable for Joystick Encoder applications.
The HT82J30A is under development and will be avail-
able soon.
