device numbering conventions
Figure 12 illustrates the numbering and symbol nomenclature for the TMS370Cx9x family.
TMS 370 C 0 9 0 A FN L
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:
9 = ’x9x devices containing the following modules:
– Timer 1
– Analog-to-Digital Converter 3 (ADC3)
Memory Size:
0 = 4K bytes
2 = 8K bytes
Temperature Ranges:
A = – 40°C to 85°C
L = 0°C to 70°C
T = – 40°C to 105°C
Packages:
FN = Plastic Leaded Chip Carrier
FZ = Ceramic Leaded Chip Carrier
N = Plastic Dual-In-Line
JD = Ceramic Dual-in-Line
ROM and EPROM Option: 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 mode can be either:
– Enabled
– Disabled
None = For EPROM device, standard watchdog, divide-by-4
clock, and low-power modes are enabled
