HT82M75R/HT82M75RE/HT82M75REW HT82K75R/HT82K75RE/HT82K75REW 2.4GHz Transceiver 8-Bit OTP MCU
Features
· Operating voltage: · All I/O pins have falling and rising edge wake-up
fSYS= 6MHz: 1.8V~3.3V
· Internal 6MHz RC oscillator for fSYS · Power down and wake-up functions to reduce
function
· Single 16-bit internal timer with overflow interrupt
and timer input
· SPI interface shared with I/O lines · Low voltage reset function (LVR) for DC_DC output
power consumption
· Two bit to define microcontroller system clock
(fSYS/1, fSYS/2, fSYS/4)
· All instructions executed in one or two machine
controlled by configuration option
· Built-in DC/DC to provide stable 2.8V, 3.0V, 3.3V
cycles
· Table read instructions · 63 powerful instructions · 6-level subroutine nesting · Bit manipulation instruction · Program Memory: 4K´15 · Data Memory: 128´8~160´8 · Watchdog Timer function · Up to 40 bidirectional I/O lines with pull-high options
with error ±5% selected by configuration options
· Low voltage detector (LVD) with levels
1.8V/2.0V/2.2V/2.5V/2.8V ±5% for battery input (BAT_IN) selected by application program
· Wide range of available package types · Optional Peripheral -- EEPROM Memory with
128´8 capacity
· Optional Peripheral -- RF Transceiver with 2.4GHz
RF frequency
General Description

Note:
(1) There is an additional peripheral known as the Data EEPROM with capacity of 128 bytes in HT82M75RE and HT82K75RE devices. All information related to the Data EEPROM will be described in the following EEPROM Data Memory section. (2) There are additional peripherals named RF Transceiver with RF frequency of 2.4GHz and Data EEPROM with capacity of 128 bytes in HT82M75REW and HT82K75REW devices. All information related to the RF Transceiver and EEPROM Data Memory will be described in the corresponding section respectively. (3) As devices exist in more than one package format, the table reflects the situation for the package with the most pins.
