M27C400190C6

The M27C400190C6 belongs to M27C4001 family which is a 4 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). A new pattern can then be written to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27C4001 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages. The FDIP32W (window ceramic frit-seal package) and LCCC32W (leadless chip carrier package) have a transparent lid which allow the user to expose the chip to ultraviolet light to erase the bit pattern. It is ideally suited for micro- processor systems requiring large programs and is organised as 524,288 by 8 bits.

The features of M27C400190C6 can be summarized as (1)5V ± 10% supply voltage in read operation; (2)access time: 35ns; (3)low power consumption: active current 30mA at 5MHz standby current 100A; (4)programming voltage: 12.75V ± 0.25V; (5)programming time: 100s/word; (6)electronic signature manufacturer code: 20h device code: 41h.

The absolute maximum ratings of M27C400190C6 are (1)TA ambient operating temperature(3)40 to 125 °C; (2)TBIAS temperature under bias: 50 to 125 °C; (3)TSTG storage temperature: 65 to 150 °C; (4)VIO(2) input or output voltage (except A9): 2 to 7 V; (5)VCC Supply Voltage: 2 to 7 V; (6)VA9 (2) A9 voltage: 2 to 13.5 V; (7)VPP program supply voltage: 2 to 14 V(2. Minimum DC voltage on Input or Output is 0.5V with possible undershoot to 2.0V for a period less than 20ns. Maximum DC voltage on Output is VCC +0.5V with possible overshoot to VCC +2V for a period less than 20ns. 3. Depends on range.).
