AT89LP828-JU

The AT89LP828-JU is a low-power CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory, manufactured by Atmel (now a part of Microchip Technology). It is based on the high-performance AT89LP800 microcontroller architecture and features on-chip Flash memory, 10-bit A/D converter, watchdog timer, and other peripherals.

Description:

The AT89LP828-JU is a low-power microcontroller designed for battery-powered applications and other energy-sensitive systems. It features an 8-bit CPU with a maximum clock frequency of 8 MHz, providing high computational performance while maintaining low power consumption. The device is available in a small-outline integrated circuit (SOIC) package, making it suitable for compact and space-constrained applications.

Features:

1. 8K bytes of in-system programmable Flash memory for code storage.
2. 128 bytes of SRAM for data storage.
3. 256 bytes of EEPROM for non-volatile data storage.
4. 10-bit A/D converter with up to 8 channels.
5. Watchdog timer for system reliability.
6. Two 16-bit timer/counters with PWM and capture/compare modes.
7. Two communication interfaces: one UART and one SPI.
8. 6-channel programmable interrupt controller.
9. Low-power modes: Idle, Power-down, and Power-save.
10. On-chip oscillator with calibration capability.
11. In-system programming and debugging via the ISP and ICP interfaces.
12. Active-high reset input.
