S3C8235

The S3C8235 is designed as one kind of single-chip CMOS microcontrollers which is fabricated using the highly advanced CMOS process, based on samsung's latest CPU architecture. It is a microcontroller with a 16K-byte mask-programmable ROM embedded.

S3C8235 has many features. (1)SAM88RC CPU core. (2)16K-bytes ROM. (3)632-bytes RAM. (4)Crystal, ceramic, RC. (5)Crystal for subsystem clock. (6)CPU clock divider (1/1, 1/2, 1/8, 1/16). (7)78 instructions. (8)IDLE and STOP instructions added for powerdown modes. (9)400ns at 10MHz fosc (minimum). (10)16 interrupt sources with 16 vector. (11)8 level, 16 vector interrupt structure. (12)Total 32 bit-programmable pins. (13)One programmable 8-bit basic timer (BT) for oscillation stabilization control or watchdog timer function. And so on.

Some absolute maximum ratings of S3C8235 have been concluded into several points as follow. (1)Its supply voltage would be from -0.3V to +6.5V. (2)Its input voltage would be from -0.3V to Vdd+0.3V. (3)Its output voltage would be from -0.3V to Vdd+0.3V. (4)Its output current high would be -18mA for one IO pin active and would be -60mA for all IO pins active. (5)Its output current low would be 30mA for one IO pin active and would be 100mA for total pin current for port. (6)Its operating temperature range would be from -40°C to 85°C. (7)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to S3C8235.

Also some electrical characteristics are concluded as follow. (1)Its operating voltage would be min 2.7V and max 5.5V for fCPU=10MHz and would be min 2.0V and max 5.5V for fCPU=4MHz. (2)Its input high voltage would be min 0.8Vdd and max Vdd. (3)Its input low voltage would be max 0.2Vdd. And so on.
