• Possible to use LCD drive output pins as output ports (Max. 16 pins. mask option selectable)

• On-chip melody function ........ 3 octaves × 2 channels

• On-chip segment PLA

The LCD driver can be used to support any LCD pannel layout without software processing.

• On-chip step-up/step-down circuit.

• Shipping style : chip or FLP-64

Note) When mounting the QIP package on the board, do not dip it in solder.

Software Features

• Powerful instruction set : 92 instructions

• Table read instruction (possible to set table in all ROM areas).

• 1 subroutine stack level.

• 15 bits time base timer.

- Deliver and overflow signal every 32ms or 64ms, 100ms and 500ms.

• HALT function.

Development Support System

The development support system for the LC5738 applications consists of the following support tools :

(1) Manual

(a) User’s Manual : LC5738 user’s manual

(b) Tool Manual : LC5738 tool manual

(2) Development support tools

(a) Tools for developing the LC5738 application programs.

- MS-DOS machine

- Assembler (LC5738. EXE)

- Mask option selections program (SU5738. EXE)

(b) Tools for evaluating the LC5738 application systems.

- Evaluation chip : LC5797

Note 1) Since the evaluation chip LC5797 differs LC5738 with RAM capacity, be sure to check the RAM capacity

when preparing or debugging programs.

LC5738 : 48×4 bits, LC5797 : 256×4 bits

Note 2) When developing programs, take care of the DPH value. The usable DPH values are 0 to 2 except ROM bank

selection.

We will be free from any blame even if you use DPH=3 to FH for RAM addressing.

- Evaluation chip board : TB5738

Note) The application evaluation board is constructed by the user.

LCD or LEDs may be used for display.

- Evaluation board : EVA520 (monitor ROM : SCR5738)

Note) The EVA-520 is a modified version of the EVA-420 whose monitor ROM is replaced by the SCR-5738.

- Display and mask-option data control board : DCB-1 (Rev.3.3)
