§ General Description:
TTP259 MCU is an easy-used 4-bit CPU base microcontroller. It
contains 4032-word ROM 384-nibble RAM time base timer/counter
interrupt service IO control hardware PWM output IIC function LVR and
touch pad feature for specified applications. The device is also suitable for
diverse simple applications in control appliance and consumer product.
§ Features:
1. Tontek RISC 4-bit CPU core
2. Total 26 crucial instructions and two addressing mode
3. Most instructions need 1 word and 1 machine cycle(2 CPU clocks) except
read table instruction(RTB)
4. Advance CMOS process
5. Working memory with 4032*16 program ROM and 384*4 SRAM
6. 4-level stacks
7. Operating voltage: 2.4V~5.5V(LVR=2.2V); 3.3V~5.5V(LVR=3.0V);
2.2V~5.5V(LVR OFF)
8. System operating frequency: (at VDD=5V)
. High speed system oscillator (OSCH)
Built-in RC oscillator: 4MHz(typical)
. Low speed peripheral oscillator (OSCL)
Built-in RC oscillator: 16KHz(typical)
9. Provide 7 IO+16 touch pad or 23 general programmable IO
IO port built-in key wake-up feature enable by software setting
Provide external interrupt inputs
Provide internal signal outputs, like PWM
