W78E052DDG 8051 Microcontroller (Pack of 5)

400.00Rs. 360.00Rs.

The W78E054D/W78E052D series is an 8-bit microcontroller which can accommodate a wider fre-
quency range with low power consumption. The instruction set for the W78E054D/W78E052D series is
fully compatible with the standard 8052.
The W78E054D/W78E052D series contains 16K/8K bytes Flash EPROM programmable by hardware
writer; a 256 bytes RAM; four 8-bit bi-directional (P0, P1, P2, P3) and bit-addressable I/O ports; an ad-
ditional 4-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. The-
se peripherals are supported by 8 sources 4-level interrupt capability. To facilitate programming and
verification, the Flash EPROM inside the W78E054D/W78E052D series allows the program memory to
be programmed and read electronically. Once the code is confirmed, the user can protect the code for
