device numbering conventions

Figure 7 illustrates the numbering and symbol nomenclature for the TMS370Cx32 family.

370

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

3 = Mask ROM, No Data EEPROM

7 = EPROM

Device Type:

32 = x32 device containing the following modules:

– Analog-to-Digital Converter 1

– Programmable Acquisition and

Control Timer (PACT)

Memory Size:

2 = 8K bytes

Temperature Ranges:

A = –40

°C to 85°C

L =

°C to 70°C

T = –40

°C to 105°C

Packages:

FN = Plastic Leaded Chip Carrier

FZ = Ceramic Leaded Chip Carrier

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 or

– A hard watchdog or

– A simple watchdog

The clock can be either:

– Divide-by-4 clock or

– Divide-by-1 (PLL) clock

The low-power modes can be either:

– Enabled or

– Disabled

A = For EPROM device, a standard watchdog, a divide-by-

4 clock, and low-power modes are enabled
