1. Device Overview

XG836 is an 8-bit high performance, low cost MCU which bases on RISC architecture. It is easy to use to deal with analog signal, for example, measurement applications with sensor. The XG836 has an embedded 10-bit analog to digital converter (ADC) with 16 channels, two pulse width modulators (PWM) and one 8-bit digital to analog converter (DAC). It also improved some internal characteristics, such as Halt Function, Wake-up Function, Oscillator Selection, and Programmable Frequency Prescaler. So, XG836 is very flexible for use, and just need least extra parts for cutting down the cost. For these advantages and good characteristics, such as Integrated A/D, Integrated D/A, Integrated PWM, low cost, high performance, flexible Input/Output, and low price, XG836 is very suitable for applications such as Sensor signal process, Motor drive, Industry control, Consumed product, and subsystem controller etc.

XG836 uses Reduced Instruction Set, and it has 256 bytes RAM, the user can easily visit the ROM and RAM but no need to change program page. The special function registers have same addressing mode with RAM

XG836 is One-Time Programmable (OTP), and user’s program can be easily and effectively emulated by our emulator. It provides an effective way for users to develop their program.

-          44 universal I/O ports

-          There are two more inputs when use internal RC oscillator

· Ambient operating temperature:  0 ~ 70°C

 

· Operating voltage range:  2.3 ~ 5.5V

 

· Operating Frequency range

1.       Crystal mode: DC~20MHz at 5V,  DC~8MHz at 3V,

2.       RC oscillator mode: 3~20MHz at 5V, 3~8MHz at 3V,

 

· Supply current of XG836 at 6MHz, 5V, 25°C

1.       Normal Mode:

It depends on the level of the LDO,

when LDO=3volt, the operating current <1.5mA (no load and transition on all I/Os).

2.       Sleep Mode:

< 4.5uA, when LDO on

< 1.5uA, when LDO off
