EU1010

The EU1010 is an OTP type 8-bit micro-controller with 2 channels of 10-bit A/D converter using advanced CMOS process. The EU1010 is specially designed for various industrial field applications. The EU1010 incorporates two sets of 8-bit timer/counters, where timer0/1 is specially designed for PWM (Pulse Width Modulation) generator. There are 8 I/O ports in EU1010.Considering form factor and manufacturability, the EU1010 is packaged into 10-pin non-JEDEC-standard compact-size SOP.

Features of the EU1010 are:(1)2.2V to 5.5V input voltage range; (2)8 I/O ports; (3)RAM size: 128 x 8 bits; (4)the STACK RAM is included; (5)program ROM size: 4K x 8 bits OTP; (6)2 channels 10 bits A/D converter input source; (7)one set of 16-bit down count timer and one set of 8-bit timer; (8)operating temperature: -40 to +125; (9)build-in low voltage reset (LVR) circuit; (10)oscillator: internal RC oscillation.The stack pointer is an 8-bit register that is used to control the addressing of the variable-length stack.The stack pointer is automatically incremented and decremented under control of the microprocessor the perform stack manipulations under direction of either the program or interrupts. The stack allows a simple implementation of nested subroutines and multiple level interrupts. The stack pointer is initialized by the user's software.

The absolute maximum ratings of the EU1010 can be summarized as:(1)storage temperature:-40 to 125;(2)operating temperature: -40 to +125.The EU1010 is built in Low-Voltage-Reset circuit to detect and against power noise. The low voltage reset will be active when Vdd is dropped lower than 2.4V. Note that, in STOP mode, low voltage reset function will be disabled by hardware. The low voltage reset function will be active when CPU is not working in STOP mode.At this condition, operating current could be down less than 1A. Only input signal from high to low of PB ports can release the chip from STOP mode. When STOP mode is released by PB ports, program counter will execute next instruction of "STA $ 0FH". If PB interrupt is enabled, PBINT=1, PB interrupt subroutine will be activated first.
