Microchip Technology, Inc. Integrated Circuits (ICs) - Interface - Specialized KBC1122P-AJZS

The KBC1122P-AJZS is an integrated Keyboard/System Management Controller from Quarktwin Technology Ltd. It features a high-performance 8051 microcontroller and supports a variety of interfaces including LPC, SPI, and a shared FlashROM interface. The device operates at 3.3V with 5V tolerant buffers and is compliant with ACPI 1.0b/2.0 and PC99a/PC2001 standards. This controller includes advanced power management capabilities with two power planes, allowing for low standby current in sleep mode and intelligent auto power management. It also integrates Direct Battery Management with SMSC SentinelAlert!, which includes an 8-channel ADC and a 3-channel DAC, facilitating analog monitoring and control. The KBC1122P-AJZS supports multiple low power-down modes and features a robust set of I/O options, including 92 general-purpose I/O pins, three independent PS/2 ports, and programmable pulse-width modulator outputs. Additionally, it provides a comprehensive set of timers, counters, and communication interfaces, making it suitable for applications requiring efficient system management and control. The product is housed in a 156-pin DQFN lead-free RoHS compliant package.
