device numbering conventions
Figure 15 illustrates the numbering and symbol nomenclature for the TMS370Cx7x family.
TMS 370 C 7 7 7 A FN T
Prefix: TMS = Standard prefix for fully qualified devices
SE = System evaluator (window EPROM) that is used for
prototyping purpose
Family: 370 = TMS370 8-Bit Microcontroller Family
Technology: C = CMOS
Program Memory Types:
0 = Mask ROM
7 = EPROM
Device Type:
7 = ’x7x device containing the following modules:
– Timer 1
– Timer 2A
– Analog-to-Digital Converter 1
Memory Size: 7 = 24K bytes
Temperature Ranges:
Packages:
ROM and EPROM Option:
A = – 40°C to 85°C
L = 0°C to 70°C
T = – 40°C to 105°C
FN = Plastic Leaded Chip Carrier
FZ = Ceramic Leaded Chip Carrier
NM = Plastic Shrink Dual-In-Line
JN = Ceramic Shrink Dual-in-Line
A = For ROM device, the watchdog timer can be configured
as one of the three different mask options:
– A standard watchdog
– A hard watchdog
– A simple watchdog
The clock can be either:
– Divide-by-4 clock
– Divide-by-1 (PLL) clock
The low-power modes can be either:
– Enabled
– Disabled
A = For EPROM device, standard watchdog, divide-by-4
clock, and low-power modes are enabled
