The AT89LS52 is a low-voltage, high-performance CMOS 8-bit microcontroller manufactured by Atmel. It features 8K bytes of in-system programmable Flash memory, 256 bytes of internal RAM, 32 programmable I/O lines, three 16-bit timer/counters, and a full duplex UART serial channel. The device is compatible with the industry-standard 80C51 instruction set and pinout, making it a versatile choice for embedded control applications.
Operating from 2.7V to 4.0V with a fully static 0 Hz to 16 MHz clock, the AT89LS52 supports low-power Idle and Power-down modes. It includes a watchdog timer, dual data pointer, power-off flag, and eight interrupt sources. The on-chip Flash allows in-system programming via byte or page modes, with an endurance of 10,000 write/erase cycles.
The AT89LS52-16AU is supplied in a 44-TQFP (10x10 mm) surface-mount package, suitable for compact designs. It is available in a green (Pb/halide-free) packaging option, supporting RoHS compliance.
The operating voltage range is 2.7V to 4.0V.
The package is 44-TQFP (10x10 mm) with surface mount.
The operating temperature range is -40°C to 85°C (TA).
The part is listed as RoHS3 compliant and is available in a green (Pb/halide-free) packaging option, but the compliance status is unverified and should be confirmed.
The core processor is an 8051 8-bit CPU.
The maximum clock frequency is 16 MHz, with fully static operation down to 0 Hz.
It has 8KB (8K x 8) of in-system programmable Flash memory with 10,000 write/erase cycles endurance.
