Holtek Semiconductor HT27C010
The HT27C010 chip family is a low-power, 1024K (1,048,576) bit, +5V electrically one-time programmable (OTP) read-only memories (EPROM). This eliminates the need for WAIT states in high-performance microprocessor systems. The HT27C010 has separate Output Enable (OE) and Chip Enable (CE) controls which eliminate bus contention issues.| Part No. | HT27C010 |
