Visão Geral
Description
- Core: 8051-compatible with 8KB Flash memory for program storage.
- Speed: Operates at up to 24MHz (indicated by "24" in the part number).
- I/O: 32 programmable pins (4 ports, 8 bits each).
- Timers/Counters: Three 16-bit timers.
- Communication: UART, SPI (via hardware).
- Package: 40-pin PDIP ("PU" denotes plastic DIP package).
- Power: 4V–5.5V supply, low-power idle/power-down modes.
Ideal for embedded systems, industrial control, and DIY projects due to its simplicity and legacy 8051 architecture. The "S" in the name signifies In-System Programmable (ISP) Flash memory via SPI, enabling easy firmware updates.
Equivalent
1. AT89C52 (older, no ISP)
2. AT89LP52 (low-power variant)
3. P89V51RD2 (NXP, higher flash)
4. STC89C52 (STC, China-based)
5. DS89C450 (Maxim, faster)
For modern replacements, consider AT89S8253 (more features) or ATmega8515 (AVR core). Verify pin compatibility and features before substitution.
