I/O Controller USB and PS/2 Controller 0.02A 24-Pin PDIP

The CY7C63743 is a family of 8-bit RISC One Time Programmable (OTP) microcontrollers with a built-in 1.5-Mbps USB Serial Interface Engine (SIE). The microcontroller features 35 instructions that are optimized for USB applications. In addition, the microcontroller features 128 bytes of internal RAM and either 2 or 4 Kbytes of program memory space. The Cypress USB Controller accepts a 6-MHz ceramic resonator as its clock source. This clock signal is doubled within the chip to provide a 12- MHz clock for the microprocessor. The microcontroller features two ports of up to sixteen general purpose I/Os (GPIOs). Each GPIO pin can be used to generate an interrupt to the microcontroller. Additionally, all pins in Port 1 are equipped with programmable drivers strong enough to drive LEDs. The GPIO ports feature low EMI emissions as a result of controlled rise and fall times and unique output driver circuits. The Cypress microcontrollers have a range of GPIOs to fit various applications; the CY7C63743 has twelve GPIOs and the CY7C63743 has sixteen GPIOs. Notice that each part has eight ‘low-current’ ports (Port 0) with the remaining ports (Port 1) being ‘high-current’ ports.
