LC5852N
Four-Bit Single-Chip Microcontroller with
On-Chip LCD Drivers for Small-Scale Control in
Medium-Speed Applications
Overview
The LC5852N is a high-performance four-bit single-chip
built-in LCD driver microprocessor that provides a variety
of attractive features including low-voltage operation and
low power dissipation. The LC5852N was developed as an
upwardly compatible version of the LC5851N and
provides a ROM capacity increased from 1024 to 2048 15-
bit words and a RAM capacity increased from 64 × 4 bits
to 128 × 4 bits.
Applications
• System control and LCD display in cameras, radios and
similar products
• System control and LCD display in miniature electronic
test equipment and consumer health maintenance
products
• The LC5852N is optimal for end products with LCD
displays and, in particular, for battery operated products.
Features
The LC5852N is an upwardly compatible version of the
LC5851N and, as such, has the following features.
• Extremely broad allowable operating ranges
