FS98O02
General Description
The FS98O02 is a high performance, low cost 8-bit MCU with 2k program EPROM, 128-byte data RAM, one 14-bit ADC, 12-bit GIO, and 4 × 12 LCD driver.
With a few external passive components such as resistors and capacitors, the FS98O02 can be easily implemented to form a simple portable tire gauge, voltage panel meter, or manual range DMM, etc. Especially, FS98O02’s EPROM could be written by program instruction, so users can write table or calibration data in the unused EPROM address more than one time.
Feature
| • | 8-bit RISC CPU core with 39 single word instructions. |
| • | Embedded 2k x 16 program ROM（07ffH isn’t usable by user）, 128-byte data RAM. |
| • | Instruction Programmer Function. |
| • | Operating voltage is from 2.4V to 3.6V. |
| • | Operating current is about 1.5mA; sleep current is about 2μA. |
| • | Embedded internal 1MHz / 4MHz oscillator. |
| • | 4-level hardware stacks. |
| • | 3 Interrupt sources（external: input port 1<0>, internal: timer, ADC）. |
| • | One 14-bit noise free ADC. |
| • | Embedded voltage regulator（2.5V / 3.6V regulated output）. |
| • | Embedded Voltage Doubler（3V / 2xVDDP pumped output）. |
| • | 4-bit Input Port and 8-bit bi-directional I/O port including 1-bit for buzzer output. |
| • | Embedded Low Voltage Reset（LVR）and Low Battery Detector（LBD）. |
| • | 4 x 12 LCD driver（3V peak-to-peak）. |
| • | Watchdog timer. |
