description (continued)
The TMS28F004Axy is offered in a 512K-byte organization only. The operation for this device is the same as
the TMS28F400Axy and is offered in the same voltage configurations. TMS28F004Axy can be substituted for
the byte-wide TMS28F400Axy with the latter being the generic name for this device family.
Embedded program and block-erase functions are fully automated by the on-chip write state machine (WSM),
simplifying these operations and relieving the system microcontroller of secondary tasks. WSM status can be
monitored by an on-chip status register to determine progress of program/erase tasks. The device features
user-selectable block erasure.
The configurations are as follows:
The TMS28F400ASy configuration has the auto-select feature that allows the user alternative read and
program/erase voltages. Memory reads can be performed using 3.3-V V
CC
for optimum power
consumption or 5-V V
CC
for device performance. Erasing or programming the device can be accomplished
with 5-V V
PP
, which eliminates having to use a 12-V source and/or in-system voltage converters.
Alternatively,12-V V
PP
operation exists for systems that already have a 12-V power supply, which provides
faster programming and erasing times. This configuration is offered in two temperature ranges: 0
°
C to 70
°
C
and –40
°
C to 85
°
C.
The TMS28F400AEy configuration offers the auto-select feature of the TMS28F400ASy with an extended
V
CC
range of 2.7-V to 3.6-V (3-V nominal). Memory reads can be performed using 3-V V
CC
, for more efficient
power consumption than the ’ASy device.
The TMS28F400AMy configuration offers a 3-V or 5-V memory read with a 12-V program and erase. This
configuration is intended for low 3.3-V reads and the fast programming offered with the 12-V V
PP
and 5-V
V
CC
. This configuration is offered in two temperature ranges: 0
°
C to 70
°
C and – 40
°
C to 85
°
C.
The TMS28F400AFy configuration offers a 5-V memory read with a 5-V or 12-V program and erase. This
configuration is intended for systems using a single 5-V power supply. This configuration is offered in three
temperature ranges: 0
°
C to 70
°
C, – 40
°
C to 85
°
C, and – 40
°
C to 125
°
C.
The TMS28F400AZy configuration offers a 5-V memory read with a 12-V program and erase for fast
programming and erasing times. This configuration is offered in three temperature ranges: 0
°
C to 70
°
C,
– 40
°
C to 85
°
C, and – 40
°
C to 125
°
C.
The y in the device name represents a T for top or B for bottom boot-block configuration.
All configurations of the TMS28F400Axy are offered in a 44-pin plastic small-outline package (PSOP) and a
48-pin thin small-outline package (TSOP). The TMS28F004Axy is offered in a 40-pin TSOP only. Both the 40-pin
and 48-pin TSOP are offered for the 0
°
C to 70
°
C and – 40
°
C to 85
°
C temperature ranges only.
