Key Features
Overview
Leap LER-123A UV EPROM Eraser: Professional Memory Management Solution
The Leap LER-123A represents the gold standard in UV EPROM erasing technology, delivering reliable performance for electronic design engineers maintaining legacy systems. This professional-grade unit accommodates up to 64 EPROM devices (24-pin × 0.6") in its spacious anti-static foam-lined tray, making it ideal for development environments and production applications.
Constructed with robust steel housing, the LER-123A features a powerful 10W mercury vapour UV tube operating at the optimal 253.7nm wavelength for complete memory erasure. The integrated electronic starter extends tube life whilst ensuring consistent performance. A precision mechanical timer provides adjustable exposure from 0-60 minutes, with typical erasure completing in approximately 15 minutes.
Enhanced Safety Features
User protection is paramount with automatic UV shut-off when the drawer opens, preventing accidental exposure to harmful radiation. An LED status indicator confirms tube operation, whilst the sealed construction contains all UV emissions within the unit.
Essential for embedded development, legacy system maintenance, and prototype work, the LER-123A ensures your valuable EPROM inventory remains functional and reprogrammable. Its compact footprint (37cm × 18cm × 10cm) fits comfortably on any workbench whilst delivering industrial-grade reliability.

Frequently Asked Questions
Have a Question?
-
What accessories are included with the LER-123A EPROM eraser?
The LER-123A includes the main unit, comprehensive user manual, and AC power cord. The anti-static foam tray is pre-installed, and the 10W UV tube is factory-fitted for immediate operation upon delivery.
-
Will room lighting or sunlight affect EPROMs stored near the LER-123A?
Normal indoor lighting poses no risk to EPROMs. However, direct sunlight can erase EPROMs over weeks, so always keep the protective labels on EPROM windows when not intentionally erasing. The LER-123A's sealed construction prevents any UV leakage.
-
Can the LER-123A erase multiple EPROM types simultaneously?
Yes, the large tray capacity allows erasing different EPROM types simultaneously as long as they all require similar exposure times. All devices receive uniform UV exposure across the entire erasure area.
-
What maintenance does the UV tube require in the LER-123A?
The 10W UV tube should be replaced approximately every 2,000 hours of operation or annually for optimal performance. The electronic starter system helps extend tube life compared to conventional starters.
-
Does the LER-123A work with modern EEPROM or flash memory devices?
No, the LER-123A is specifically designed for UV-erasable EPROM devices with quartz windows. Modern EEPROM and flash memory devices use electrical erasure and are not compatible with UV light erasure methods.
-
Is the LER-123A safe to operate in office environments?
Yes, the LER-123A includes comprehensive safety features including automatic UV shut-off when the drawer opens, complete UV containment within the steel housing, and LED status indication. The unit prevents accidental exposure to harmful ultraviolet radiation.
-
What types of EPROM packages can the LER-123A accommodate?
The LER-123A accommodates up to 64 devices in 24-pin packages, 50 devices in 32-pin packages, or 40 devices in 40-pin packages. The anti-static foam tray measures 26.5cm × 15cm and accepts standard 0.6" pitch devices.
-
How long does it take to completely erase an EPROM with the LER-123A
The LER-123A typically erases EPROMs in approximately 15 minutes, though exposure times from 0-60 minutes can be set depending on chip type and erasure requirements. The powerful 10W UV tube ensures complete erasure at the optimal 253.7nm wavelength.
