KS57C3016-91

The KS57C3016-91 is designed as a single chip CMOS microcontroller for very high performance using samsung's newest 4-bit development approach, SAM4(samsung arrangeable microcontrollers). With an up-to-16-digit LCD direct drive capability, 4-channel A/D converter, 8-bit timer/counter, PLL frequency synthesizer and 6-channel PWM outputs, it offers you an excellent design solution for a wide variety of applications, especially those requiring DTS support.

It has many features. (1)For the memory 1024x4-bit RAM and 16-384x8-bit ROM. (2)For its 55 IO pins the input only 4 pins. (3)Output only: 12pins for bit output or LCD seg output. (4)I/O 23 pins (16 I/O pins are N-channel, open drain). (5)For LCD controller/driver, maximum 16-digit LCD direct drive capability. (6)Display modes: static, 1.2duty (1/2 bias). (7)1/3 duty (1/2 or 1/3 bias), 1.4 duty (1/3 bias). (8)For 8-bit basix timer four interval timer functions. (9)For bit swquential carrier, supports 16-bit serial data transfer in arbitrary format. And so on.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its supply voltage would be from -0.3V to 7.0V. (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 -15mA for one I/O port active and would be -30mA for all I/O ports active. (5)Its output current low would be +30mA peak value. (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 device.

Also some electrical characteristics are concluded as follow. (1)Its input high voltage would be min 0.7Vdd and max Vdd. (2)Its input low voltage would be max 0.3Vdd. (3)Its output high voltage would be min Vdd-1.0V. (4)Its output low voltage would be typ 0.8V and max 2V. And so on.
