The AT89S4051-24PU is a low-voltage, high-performance 8-bit CMOS Microcontroller with 4kB of In-system programmable (ISP) flash program memory. The device is manufactured using high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with flash on a monolithic chip, the AT89S4051 is a powerful microcontroller which provides a highly-flexible solution. It is designed with static logic for operation down to zero frequency and supports two software-selectable power saving modes. The idle mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the disabling all other chip functions until the next external interrupt or hardware reset.

• Compatible with MCS®51 products
• 0 to 24MHz Fully static operation
• Two-level program memory lock
• 256 x 8-bit Internal RAM
• 15 Programmable I/O lines
• Two 16-bit timers/counters
• Six interrupt sources
• Programmable serial UART channel
• Direct LED drive outputs
• On-chip analog comparator with selectable interrupt
• 8-bit PWM (Pulse-width modulation)
• Low power idle and power-down modes
• Brownout reset
• Enhanced UART serial port with framing error detection and automatic address recognition
• Internal power-on reset
• Interrupt recovery from power-down mode
• Programmable and fuseable x2 clock option
• Four-level enhanced interrupt controller
• Power-off flag
• Flexible programming (byte and page modes)
