See all from this product rangeProduct Overview
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

- 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)
